BEIJING - A message from President Bush to North Korean leader Kim Jong Il will be delivered Monday in Pyongyang -- via two Chinese officials. Beijing now meets quarterly with Mr. Kim, the most contact the unpredictable North has with any outside party. Whether Vice Foreign Minister Wu Dawei and Vice Premier Hui Liangyu will surprise Kim Jong Il and exert real pressure is unclear.

With an international diplomatic effort under way a week after North Korea tested seven missiles, China has proposed informal six-party talks as a way to move the process along.

That is less than the US hoped for from China. But since China insists that it will veto any UN sanctions against the North, the US will accept such talks, according to envoy Christopher Hill.

All told, Beijing would appear key to shaping how the world deals with the defiant Kim. Yet from the moment Kim launched his missiles, China has denied it has clout; it politely insists that the US has the central role.

Since 2003, China has embarked on a historic effort to prop up and aid North Korea -- a state it had the frostiest relations with for more a decade. Now, $2 billion in aid gives Beijing unprecedented access -- something China is reluctant to squander, to "mix aid and diplomacy," as a Chinese scholar here puts it.

"China's influence on North Korea is more than it is willing to admit, but far less than outsiders tend to believe," says a recent report by the Seoul branch of the International Crisis Group.

To outsiders, it appears that a rising China -- running a lifeline of energy and food to its poor comrade - ought to have clout in Korea, as it holds more carrots and sticks than anyone. It seems axiomatic that Beijing can simply apply ancient Chinese wisdom and modern Chinese might to stop Kim's nuclear ambition. Both states are communist, wear green and red uniforms, fought the US together, and share borders and history. China is the only country with easy access, as well as trade and tourism, to the North.

"China does have leverage, but it is afraid it may overplay its hand," says Joseph Cheng, head of the political science department at City University in Hong Kong.

Since Kim Jong Il's July 4 missile shots, voices from Sandy Berger, President Clinton's security adviser, to John Bolton, US ambassador to the UN, have argued that "China is the key" to dealing with North Korean belligerence. It has become nearly a mantra in Washington. Twelve months ago, it was an article of faith in senior White House circles, misplaced or not, that China would deliver a deal with Kim to dismantle his nuclear program. Yet this did not happen.

Instead, with the US preoccupied in Iraq, China embarked on a quiet policy of self-interest: to strengthen North Korea. That policy helps to maintain the North as a "buffer state" between China and South Korea.

China does not want the North to collapse, and for US troops to fill the vacuum and appear on its northeast border. China has hosted Kim, and moved relations away from a bad patch in the 1990s, during the North's epic famine, when China asked for cash payments for food instead of barter.

In the past two years, Chinese officials have told Kim that he can reform his state along socialist lines just as China did. China has indicated it will help with economic aid, while he retains complete political control. To now castigate Kim could wreck that formula, sources say.

In the larger sense, Kim's launch of missiles, most of which could hit long-time nemesis Japan or US bases in East Asia, puts China in the position of choosing between its North Korean comrade and an evolving consensus in the international community. So far, China has tried to please both sides.

"I'm concerned that China isn't recognizing how serious this issue is," says Zhang Liangui, head of foreign studies at the Central Party School in Beijing, in a rare dissent. "China is taking a rigid position. Yet we have long said that if China wants to be viewed as a responsible superpower, it must not be isolated in the international community."

Adding to Beijing's problems is an unresolved ideological struggle in China -- where "neo-orthodox" hard-liners who maintain contact with North Korea want China to support its revolutionary posture. There is also genuine puzzlement in Beijing over how to deal with Kim, whose founder-father, Kim Il Sung, reputedly warned him many times that China would attempt to take over his regime one day.

"I hear often that China is the key, which involves a set of policy steps Beijing can take that will bring about the outcome the allies want," says Russell Leigh Moses of People's University. "But I have yet to see anyone show how if China does X, Pyongyang will do Y."

The White House seems to have abandoned its 2003 optimism that China will harness Kim. China may agree that a nuclear peninsula and a regime that test-fires rockets is not desirable. But it isn't clear on how to force Kim to open his highly controlled state and allow international inspectors to flood in, witness his system of gulags, and bring in potentially subversive material -- all to dismantle a nuclear program he's cherished for decades. The White House seems to understand this.

Scott Snyder of Stanford University argues the US is using the same strategy that it used with China in closing down Kim's accounts in Macau. China was forced to choose between the international regulatory authority, or North Korean money-laundering behavior.

Sunday, Undersecretary of State Nicholas Burns argued on FOX News Sunday that "It's time for China to exert its influence that it does have on North Korea." Also on Sunday programs, US and Japanese officials claimed they might have the votes to support a Japan-backed resolution for sanctions against the North.

For Vice President Dick Cheney, the question of how to deal with would-be nuclear powers in Iran and North Korea is disarmingly simple.

"We don't negotiate with evil; we defeat it,'' Cheney reportedly pronounced, dismissing a State Department bid in late 2003 to make a deal with North Korea. A similar prescription was offered when moderates in the Iranian regime made a secret approach that year to begin talks with the United States.

The long history of the Cold War is replete with the issue of whether -- and how -- to talk with a mortal foe. U.S.-Soviet relations froze time and again. For two decades, there was no dialogue at all with Communist China. But in the end, American policymakers have always chosen the path of negotiation.

For Cheney -- and for President George W. Bush -- sitting down at a table with the likes of North Korea's Kim Jong Il would be an act of weakness, a lessening of American power and prestige that granted undeserved legitimacy to despised regimes.

In recent months, and most prominently last week, the Bush administration has appeared to reverse its stance, opening the door to direct talks with North Korea and Iran.

These moves are carefully constrained, reflecting in part the ongoing divisions in the Bush administration about the advisability of going down this path. Contacts with both regimes will take place only within the framework of multilateral talks and focused solely on the issue of their nuclear programs. One-on-one talks on a broader agenda, including establishing basic diplomatic relations, have been explicitly ruled out, for now.

The decision to talk seems driven in large part by the realization that defeating evil has proven to be more difficult than some in the administration assumed. After Iraq, the use of military force against Iran -- and even more so against a North Korea already probably armed with nuclear weapons -- is highly unlikely. Potential allies in imposing economic and political sanctions -- the Europeans, Russians and Chinese, along with South Korea and Japan -- won't even consider such steps without a greater show of American willingness to negotiate with the evil enemy.

Limited as it is, the significance of this shift has to be seen against the backdrop of deep resistance to such diplomatic engagement in the Bush administration.

"There is a fundamental disagreement over how to approach the North Korea problem,'' explained Richard Armitage, who served as deputy secretary of state from 2001-05.

"'Those of us at the State Department concluded: From the North Korean point of view, the nuclear issue is the only reason we Americans talk with them,'' Armitage recounted in a recent interview with the Oriental Economist newsletter. "Therefore, the North Koreans would be very reluctant to let go of the nuclear program. We knew it was going to be a very difficult process. But you have to start somewhere. You start by finding out what their needs and desires are, and seeing if there is a way of meeting those needs and desires without giving away something that is sacred to us.''

But the White House and others in the administration blocked at every turn their attempts to open direct dialogue with Pyongyang. "There is a fear in some quarters, particularly the Pentagon and at times in the vice president's office, that if we were to engage in discussions with the North Koreans, we might wind up with the bad end of the deal,'' Armitage said. "They believe that we should be able to pronounce our view, and everyone else, including the North Koreans, should simply accept it. This is not a reasonable approach.''

Six-party talks

The compromise was the decision, through the good offices of China, to convene six-party talks that included surrounding countries such as Russia, South Korea and Japan. Administration officials have argued that this format rallies others to back the United States in pressing the North Koreans, effectively isolating them.

The same argument was made for the United States to support, but not directly join, until this past week, European negotiations with Iran. As recently as April, Bush was still publicly wedded to this logic.

"With the United States being the sole interlocutor between Iran, it makes it more difficult to achieve the objective of having the Iranians give up their nuclear weapons ambitions,'' Bush said in answering questions following an April 10 speech. "It's amazing that when we're in a bilateral position, or kind of just negotiating one on one, somehow the world ends up turning the tables on us.''

Arguably, however, the opposite has been true. In the case of Iran, the Europeans, including Great Britain, have consistently urged the United States to talk directly to Iran.

An excuse not to talk

All the other partners in the six-party talks, including the closest U.S. ally, Japan, have held their own direct talks with Pyongyang and pushed the United States to do the same. Ultimately, it is the United States that has found itself isolated.

North Korean experts in the State Department had warned against relying only on this approach.

"In the case of negotiating with North Korea, more is not merrier and certainly not more efficient,'' says Robert Carlin, a longtime CIA and State Department intelligence expert on North Korea who participated in virtually all negotiations with the North from 1993-2000. "The more parties and people at the table, the greater the likelihood of posturing, and the harder it is to make concessions.''

In his view, the insistence on a multilateral approach was initially an excuse not to talk. "They didn't want bilateral talks with Pyongyang and they certainly didn't trust the State Department to conduct any such thing.''

These divisions have persisted. Last September, with the backing of Secretary of State Condoleezza Rice, the State Department's chief negotiator was finally allowed to meet his North Korean counterpart. This led to an agreement in the six-party talks last September, a compromise that conceded in principle the North Korean right to have a nuclear power reactor.

That deal prompted a backlash from Cheney and others, according to senior officials within the administration, and fresh curbs on direct contacts with Pyongyang. But the new proposal to Iran apparently also includes an offer to supply power reactors.

What still has resonance is the belief that direct talks with North Korea and Iran amount to acceptance of the regimes in power in both countries.

Resistant to deal

"Ultimately the president is, on this issue, very, very resistant to the idea of doing a deal, even a deal that would solve the nuclear problem,'' Flynt Leverett, who dealt with Iran for the Bush National Security Council, said in a recent interview. "You don't do a deal that would effectively legitimate this regime that he considers fundamentally illegitimate.''

The administration may calculate that this offer of talks will only serve to isolate Iran and shore up ties with Europe. But it may have stepped onto a slippery slope toward a bargain that will necessarily involve painful concessions to Iran and lead toward a resumption of diplomatic relations broken off almost three decades ago.

Opposition to negotiating with the enemy is deeply embedded in the Bush administration. There is, however, a precedent for a sea change -- Ronald Reagan. President Reagan came to office in the wake of the Soviet invasion of Afghanistan and the American boycott of the 1980 Moscow Olympics. Dialogue with the Soviets was halted and the staff of the Reagan National Security Council opposed any contacts with Moscow.

Reagan himself, in a famous 1983 speech, referred to the Soviet Union as an ``evil empire,'' followed two weeks later by the launching of the "star wars'' missile-defense program. Soviet leaders, we learned later, were convinced that the United States might launch a first strike. In August of that year, Soviet fighter aircraft shot down a Korean Airlines passenger jet that had strayed from its flight path, a sign of sharply increasing tension.

In the Reagan administration, against fierce internal opposition, Secretary of State George Shultz pushed to resume dialogue with the Soviets, beginning with achievable steps such as resuming grain sales. Reagan ultimately agreed, starting down a road that led to the series of dramatic summits from 1985 with incoming Soviet leader Mikhail Gorbachev.

Reagan's willingness to sit down with the "evil'' foe flowed from a sense of conviction in American strength. It is not yet evident that his Republican successor shares the same sense of confidence.

What is South Korea's strategic posture in East Asia?

After the Korean War ended in 1953, South Korea and the United States established a political and security alliance that has lasted more than half a century. "For a number of decades, South Korea primarily defined itself as a U.S. ally, with the enemy to the north," says Donald Gregg, president of the Korea Society and a former U.S. ambassador to Korea. However, South Korea is now trying to create a new role for itself in Asia. Seoul is exploring a growing economic relationship with China--which passed the United States in 2003 to become South Korea's largest trading partner--and its policy of engagement and growing cooperation with North Korea is pulling it away from the United States. "All we know for sure is that South Korea's role is no longer junior partner to the U.S.," says David Kang, a visiting professor of Asian studies at Stanford University. "The days when they would just unquestioningly follow the U.S. are over."

Kang and other experts say Seoul is beginning to shift its focus towards increasing regional ties with its Asian neighbors. The U.S.-South Korea relationship, while still strong, is not as exclusive as it has been in the past. "South Korea is still an ally of the United States ... nevertheless, it has been the most active country in promoting East Asian cooperation and integration, and will probably continue to do so," says Charles Armstrong, professor of history and director of the Center for Korean Studies at Columbia University.

What are South Korea's biggest foreign policy challenges?

Dealing with North Korea while preserving its relationship with the United States, maintaining relations with Japan, and addressing potential long-term military or economic threats from China, experts say. But "the major issue for Seoul is overwhelmingly North Korea, and everything else gets filtered through that lens," Kang says. South Korea looks to its northern neighbor with the goal of eventual reunification, and therefore seeks economic cooperation and political engagement to smooth relations and slowly move down that path. The United States, on the other hand, is primarily seeking to prevent North Korea from gaining nuclear weapons, and has refused to engage with Pyongyang until that issue is resolved.

Other experts see a disconnect between how South Korea views its role in the region and how other nations see it. South Korean officials talk of playing a "balancing" or mediating role in regional disputes, including tensions between China and Japan and the nuclear standoff between the United States and North Korea. But South Korea's "actual ability to mediate and balance is limited," says Armstrong. And while South Korean President Roh Moo-Hyun has expressed hopes of building Seoul into a logistics and business hub for the region, existing tensions on the peninsula--including international fears that North Korea is amassing a nuclear arsenal--cloud any long-term economic plans. As things stand, South Korea has the world's 11th largest economy, but not a corresponding level of political clout.

How is South Korea dealing with North Korea?

Through a policy of active engagement. In 1998, Former President Kim Dae-Jung introduced the "Sunshine Policy" aimed at improving ties with North Korea while assuring Pyongyang that Seoul is not trying to absorb it. Since then, "the degree of economic interaction between south and north has substantially increased," Armstrong says. Kim and North Korean President Kim Jung-Il met at a historic summit in 2000, and increasing progress has been made on a range of issues, from economic--increased rail links and joint projects like the Gaesung industrial complex--to social and symbolic, including cross-border family visits and Korean athletes marching together under a single flag at the Olympics. Trade between the two countries reached $697 million in 2004, and South Korea is now Pyongyang's second-largest trading partner after China.

South Korea sees engagement with North Korea as yielding far more benefits than confrontation. "South Korea is reorienting itself toward reconciliation and eventual reunification of the peninsula," Gregg says. South Korean officials say reunification would reduce the burden on each side of maintaining huge armies, help improve living standards, draw international investment, create employment, and help avert the worst possibility: open war on the Korean peninsula.

What is South Korea's relationship with China?

South Korea is developing increasingly warm relations with its giant western neighbor. "There is a real fascination with China in South Korea, and the flow of investment, exports, students, tourists, and businessmen going to China from South Korea has exploded in the last several years," Armstrong says. Bilateral trade between Seoul and Beijing reached $90 billion in 2004, a 42 percent increase from 2003. The two countries also agree politically on issues ranging from opposition to Japanese Prime Minister Junichiro Koizumi's visits to the Yasukuni war shrine, to accord on how to deal with North Korea's nuclear ambitions. China is also choosing the path of engagement with North Korea, and helping Pyongyang find a "Chinese way" to develop: that is, increasing economic openness without sacrificing political control. "On the whole, [South Korea and China] see pretty much eye to eye on the major geopolitical issues," Kang says.

Beijing, like Seoul, is investing in North Korea, which has ample natural resources--including coal, iron, and gold--and a low-cost labor force. In 2003, Chinese investment in North Korea was $1.1 million; in 2004, it ballooned to $50 million; and in 2005, it was expected to reach $85-90 million. The volume of trade between China and North Korea reached $1.5 billion in 2005, making Beijing Pyongyang's largest foreign trading partner. North Korean leader Kim Jung-Il, who rarely travels, emphasized Beijing's importance to his country by visiting China in January.

South Korea is positioning itself to be closer to an ascendant China, but trying to do it without jeopardizing existing ties with the United States. South Korea's biggest worry, experts say, is being pulled into a conflict between the United States and China over Taiwan.

What's the relationship like between South Korea and Japan?

"Very bad at the moment in terms of public diplomacy and popular opinion," Columbia University's Armstrong says. South Korean wariness of Japan dates back at least to 1910, when imperial Japan invaded Korea and ruled it as a colony for thirty-five years. During the occupation, Japanese efforts to suppress Korean language and culture earned Korean enmity. During World War II, the Japanese practice of using "comfort women"--women from occupied countries, mostly Korea, who were forced to serve as prostitutes for the Japanese army--increased the anti-Japanese feeling.

South Koreans, and others across the region, are also infuriated by Koizumi's annual visit to the Yasukuni shrine. The site honors more than two million Japanese war dead, but includes the remains of more than a dozen convicted war criminals. South Korea also has disputes with Japan over territory. Both countries claim a group of islands--and the fishing and mineral rights around them--in the Sea of Japan that the Koreans call Dokdo and the Japanese call Takeshima. And many critics in South Korea and across Asia accuse Japan of whitewashing its wartime atrocities in its grade-school textbooks.

But much of the South Korean conflict with Japan may be for domestic political consumption, some experts say. "Under the surface, I would say the degree of interaction [between Seoul and Tokyo] remains high and, in the economic realm, is rather good," Armstrong says.

How is South Korea dealing with the United States?

While experts say most South Koreans still consider the U.S.-Korean alliance the backbone of their security relationship, time has passed and attitudes are shifting. A new generation of South Koreans, assertive and nationalistic, are less mindful of the Korean War--and less grateful for American intervention in the conflict that left nearly three million Koreans dead or wounded--and more resistant to what they see as a U.S. attempt to impose its values and Washington's singular focus on terrorism. The United States has opposed South Korean engagement efforts with North Korea, and has also moved to increase its ties with Japan. The Bush administration's foreign policy, including the war on terror, its punitive stance toward North Korean nuclear weapons, and particularly the invasion of Iraq, is highly unpopular in South Korea, according to opinion surveys there.

South Koreans are also increasingly demanding more control over their country's military and political affairs. In 2004, the United States returned several military bases to Korean control, and agreed to withdraw 12,500 of the 37,500 U.S. troops currently stationed in Korea by 2008. U.S. officials, including Defense Secretary Donald Rumsfeld, had been pushing for South Korea to take more of a role in the defense of the Korean peninsula, to free up U.S. forces for deployment elsewhere. But, all differences aside, Seoul is still eager to cooperate with the United States. South Korea, with some 3,000 troops in Iraq, is the third-largest member of the U.S.-led coalition there, behind the United States and Britain.

What is the recent history of the region?

Poised between China and Japan, fought over by the United States and Russia, the Korean peninsula long has played a central role in Asia's geopolitical affairs. After World War II, Japanese colonial rule gave way to U.S. and Soviet trusteeship over the southern and northern halves of Korea, respectively. The peninsula was divided at the 38th Parallel. In 1948, the southern Republic of Korea and the northern Democratic People's Republic of Korea, under Kim Il-Sung, were established.

In 1950, North Korean forces invaded South Korea, starting a conflict that brought in China on the North Korean side and a U.S.-led UN coalition on the South Korean side. While an armistice was agreed to in 1953, a formal peace treaty was never signed. In 1954, the United States agreed to help South Korea defend itself against external aggression in a mutual defense treaty. U.S. troops have been stationed in Korea since then. In addition to this important security relationship, shared interests in the last fifty years have included fighting communism and, since the 1980s, establishing a strong democracy and fostering economic development. However, in recent years strain has emerged on a range of issues, none more important than how to handle Pyongyang.
