Last week, the world was waiting to see whether U.S. President Donald Trump would be reelected. Four days later, the verdict was in. Joe Biden, winning more overall votes than any other candidate in U.S. history, will be the 46th president of the United States.

While the United States was fixated on the final days of campaigning, China didn’t miss a beat in its aggression toward Taiwan. The day before the U.S. presidential election, Chinese aircraft flew into Taiwan’s airspace eight separate times. These military maneuvers are part of a disturbing trend of increased Chinese military activity over the past two months. Since Sept. 9, Beijing has flown near-constant sorties into Taiwan’s Air Defense Identification Zone (ADIZ), sometimes conducting as many as 30 in a day. On Sept. 21, China claimed that the median line, the boundary between the airspace of Taiwan and China that both sides had generally respected for decades, no longer existed.

These are the tense cross-strait circumstances a newly elected Biden will step into when he takes the oath of office in January. The decisions he makes concerning Taiwan will shape the future of the self-governing island, a democracy of nearly 24 million people and the 21st- largest economy in the world, as well as the tenor of U.S.-China relations regional stability.

So what can we expect from the next president on Taiwan? We can already see some differences emerge. For example, when Trump won the 2016 election, he received congratulations from Taiwanese President Tsai Ing-wen via phone. This made him the first president or president-elect to speak directly to the president of Taiwan since the United States normalized relations with Beijing in 1979. On the occasion of Biden’s election, no such phone call took place. Instead, Tsai sent her congratulations via Twitter, avoiding direct contact between the two.

This is just one anecdote. But does it suggest that Biden’s approach to Taiwan will differ greatly from that of the Trump administration?

Yes and no. The cornerstones of U.S. Taiwan policy—arms sales and strategic ambiguity—will change little under a Biden administration. The big difference will be in how Biden tries to maintain stability across the Strait.

The Trump administration has been bold in its arms sales, approving over $17 billion worth of arms over the past four years and blurring the line between offensive and defensive weaponry. Moreover, the Trump administration agreed to sell 66 F-16s to Taiwan in one of the largest arms sale packages ever offered to the island nation.

Yet while Trump earned praise for bolstering Taiwanese defenses against a possible mainland invasion, his approach to arms sales did not deviate significantly from his predecessors. The stated goal of U.S. arms sales to Taiwan is to ensure the “security, or social or economic system, of the people of Taiwan” and to further the “principle of maintaining peace and stability in the Western Pacific.” In other words, arms sales are largely dependent on the military threat Beijing poses.

For example, relations between the PRC and Taiwan deteriorated during the early 1990s, leading to the Third Taiwan Strait Crisis and a spike in U.S. arms sales to Taiwan at the beginning of the Clinton administration. Trump was also not the first president to sell high-end aircraft to Taiwan; President George H. W. Bush sold F-16s. And while Clinton, the second Bush, and Obama all decided against selling the F-16, choosing instead to help upgrade and maintain aircraft already in Taiwan’s possession, the recent sale received bipartisan support largely because of the heightened threat posed by Beijing today.

Biden will maintain similar policies, continuing to offer arms to Taipei to address the growing threat across the Strait. Biden is a strong supporter of the policy; he was one of the original senators who voted for the Taiwan Relations Act, which serves as the basis for the sales. But that doesn’t mean that he will offer similarly large packages to Taipei; some of the island’s need for weaponry and equipment has already been fulfilled through recent sales. It is also possible that Biden may try to soften the blow to Beijing by not overly publicizing sales or by notifying Beijing privately before sales are announced. But the sales themselves will continue regardless.

When it comes to America’s overall position, strategic ambiguity has guided U.S. policy on Taiwan for decades. Presidents have periodically questioned the policy, but none have gone so far as to change it.

The same can be said for Trump. Initially, the direct call between him and Tsai caused many to speculate that he may choose to support Taiwan’s independence openly. But he was cautious in the following years to avoid actions that Beijing or Taipei could construe as recognition. Indeed, despite attempts from within his party to discard strategic ambiguity, Trump limited himself to the vague, “China knows what I’m gonna do.”

Recently, there has been a flurry of debate about whether it’s time to abandon the policy as a warning to Beijing. But such views likely do not represent those of the president-elect. Biden is on record with his support of strategic ambiguity, which he has described as “reserv[ing] the right to use force to defend Taiwan but [keep] mum about the circumstances in which we might, or might not, intervene in a war across the Taiwan Strait.”

Continuing to embrace strategic ambiguity doesn’t mean Biden will be less supportive of Taiwan than Trump. Biden was the first Democratic presidential candidate to extend congratulations to Tsai when she won reelection in January. But he correctly views strategic ambiguity as the best way to deter Beijing without emboldening Taiwan. In his words, “The president should not cede to Taiwan, much less to China, the ability automatically to draw us into a war across the Taiwan Strait.”

If the main contours of U.S.-Taiwan policy remain the same, then does it make a difference who is president? Absolutely. While Biden will work towards the same goal of deterring Beijing without emboldening Taipei, he will embrace different, more effective ways for achieving it.

Trump could not protect Taiwan’s international space because he purposefully reduced U.S. influence in international institutions. He pulled out of numerous international organizations and deals, including the World Health Organization (WHO), the Trans-Pacific Partnership (TPP), Paris Climate Agreement, the United Nations Human Rights Council, and the United Nations Relief and Works Agency. So there was little that could be done when China forced Taipei out of the WHO’s World Health Assembly in 2017, where it had been an observer since a 2009 agreement. In 2020, China forced Taiwan’s exclusion even though its COVID-19 response was one of the most successful in the region, and condemnation from the State Department was largely ignored. Similarly, Taipei has also been kept at the margins of the United Nations Climate Change Conference since the United States left the Paris Agreement. And although entry into the TTP is a priority for Taiwanese leaders, Taipei lost its best path to joining without Washington to champion its candidacy.

Biden, as he has already shown through moves such as canceling Trump’s attempt to pull out of WHO, will be more involved in international institutions and strive to regain the United States’ global leadership role. This will give the United States more institutional power to advocate for Taipei’s inclusion and protect Taiwan’s international space better than the Trump administration’s unilateral efforts. Moreover, Biden is likely to reinstate the budgets for key U.S. organizations like USAID that Trump undermined and gutted. He also nominated a critic of the World Bank and IMF to oversee the U.S. role in both institutions. Reduced development aid and perceptions that American influence in the Pacific was declining have pushed countries toward China. In 2019, the Republic of Kiribati and the Solomon Islands both switched recognition from Taiwan to mainland China in exchange for multi-million dollar infrastructure deals.

A Biden administration will also work more with allies to meet the broader challenges China poses. The United States would not expect its security partners to play an integral role in any armed defense of Taiwan. But even the diplomatic support of other countries could go far in cautioning an increasingly confident Beijing.

In contrast, the Trump administration has relied mainly on unilateral options to enhance deterrence against the PRC, like freedom of navigation operations (FONOPs). These operations in which the U.S. navy sails through areas over which China has illegally declared sovereignty will likely continue under a Biden administration, but less frequently as he shifts to utilizing nonmilitary tools as well.

But the bigger change will be Biden’s tone. Trump has focused on provoking Beijing—using Taiwan as “an instrument of pushback against China.” Last month, a second high-level visit from a U.S. official to Taiwan within two months prompted China to fly 18 military aircraft across the sensitive midline on the Taiwan Strait, forcing Taipei to scramble fighter jets in response. The sale of F-16s was delayed because Trump was using it as a bargaining chip in trade deal negotiations with China.

Biden’s goal will not be to threaten Chinese interests for its own sake but to maintain the status quo across the Strait. For example, he has stated publicly that the United States should not come to Taiwan’s aid if Taiwan provokes war by declaring independence.

This more balanced approach will do much to reassure Beijing. Deterrence requires both reassurance and credible threats. The Trump administration has been effective at the former, signaling to Beijing that Washington is willing to defend Taiwan if necessary. But Washington must also avoid making Beijing believe that it will punish it no matter what, or else the United States loses the power to shape China’s potential use of force. Thus, reassuring Beijing that the United States is not attempting to change the status quo by encouraging Taiwanese independence is equally important. Hopefully, Biden will reinstate this balance.

On March 31, Taiwan’s Ministry of Foreign Affairs reported that two Chinese Air Force (PLAAF) J-11 jets crossed the median line of the Taiwan Strait. This violated the long-held tacit agreement between China and Taiwan that neither side should cross the median line.

Taiwan deemed this “an intentional, reckless & provocative action,” which triggered “a 10-minute standoff” in the air. As Asia security expert Bonnie S. Glaser notes that, if intentional, this would be the first PLAAF crossing of the median line in about 20 years. In this case, it’s likely that Taiwan, not the South China Sea, prompted Beijing’s actions.

An unresolved issue from the Chinese civil war, Taiwan has always been a “core interest” to party leaders in Beijing. Here are some key takeaways from my research on China-Taiwan relations…

On March 4, Brent Christensen, Director of the American Institute in Taiwan’s Taipei office, delivered the keynote speech at the Taiwan Democracy and Security Project's annual workshop. A video recording of the event is available below for 30 days (additionally, a transcript of Mr. Christensen's prepared remarks is available on the American Institute in Taiwan website).

An air of uncertainty remains prevalent in the Indo-Pacific region. The South China Sea continues to be in contention, with six governments exerting claims on overlapping areas. The threat of a full-blown trade war between China and the United States puts the stability of the regional (and global) economy in question. Meanwhile, the Korean peninsula appears to swing between the brink of conflict to the possibility of dramatic diplomatic breakthroughs. It was in the midst of this precarious period for the region that the third annual gathering of the U.S.-Japan Security and Defense Dialogue Series took place in Tokyo from January 30 to February 1.

The 2019 meeting was co-sponsored by the Sasakawa Peace Foundation and APARC’s U.S.-Asia Security Initiative (USASI). For the past three years, the series has convened senior Japanese and American policymakers, military leaders, scholars, and regional experts to discuss Japan's security strategy and the alliance between Japan and the United States. Support for the workshop came from the Carnegie Corporation of New York.

Since its inception in 2016, the dialogue series has provided a venue for in-depth discourse on contemporary Asia-Pacific security issues, and has helped build bridges between American and Asian academics, government and military officials, and other defense and security policy specialists. “We have continued to expand the range of attendees from the Japanese and U.S. government and military,” said USASI Director Karl Eikenberry. “This has ensured for our dialogue even greater policy relevance with each iteration.”

“The U.S.-Japan security dialogue is unique because it combines civilians and military officers, both retired and serving, which simply does not take place elsewhere,” observed Stanford Lecturer in International Policy Daniel Sneider, a regular participant. “It also avoids the sometimes-empty rhetoric about our alliance in favor of an operational, but strategically informed, approach that gets at not only what is being accomplished, but where the gaps exist in our alliance.”

Threats, Challenges, and the Appropriate Responses

The 2019 dialogue opened with a day of discussions on many of the challenges facing the U.S.-Japan security alliance, including an assessment of the latest security trends in the Indo-Pacific, as well as Japan’s new National Defense Program Guidelines (NDPG). Passed by the Japanese Cabinet only a month earlier, the NDPG was the focus of two sessions on day one, including a discussion of its implications for Indo-Pacific security, as well as a session on the guideline’s ramifications for concepts of Integrated Air and Missile Defense and Archipelagic Defense

“Unsurprisingly, the global rise of China—along with the U.S. and Japan’s separate and combined responses to PRC strategy in the Indo-Pacific Region—helped shape both our agenda and the selection of participants,” observed Eikenberry. “We were specifically interested in the implications for the maritime domain and certain operational aspects of the U.S.-Japan security alliance.”

The day one closing ceremony featured remarks from the U.S. Ambassador to Japan, the Honorable William Hagerty.

Developing Policy Recommendations, Meeting with Policymakers

Days two and three were designed for small group sessions. Referred to as “Core Group”, its U.S. and Japanese members met the morning of January 31 to review the preceding day’s workshop and develop corresponding policy recommendations. The quality and depth of the conversations underscored just how great an impact the expanded range of participants had on the resulting policy.

“Participants weren't afraid to address sensitive, big-picture questions,” said Phillip Lipscy, a Center Fellow at the Freeman Spogli Institute for International Studies at Stanford, “like the slow growth of Japanese military spending in the face of increasing regional threats and the challenges posed by unpredictable US administration policies.”

“Even as an expert of Japanese politics, I found the dialogue extremely informative and stimulating,” shared Lipscy.

Sneider agreed as well. “One thing that stood out this year, in contrast to the previous years, was a greater willingness on the part of our Japanese colleagues to air their sense of unease about and even opposition to the direction of American foreign and security policy under the Trump administration,” he said. “In the past, the American participants were much more open about their criticism of their own government, the Japanese tended to be polite—not so much this year, which made for a lively exchange on many issues.”

In the afternoon, core U.S. participants again met with the US Ambassador, along with his embassy team, as well as with senior Cabinet Office officials from the government of Japan.

Field Testing Ideas

During the second annual gathering in 2018, the dialogue began including a visit by the core workshop participants to a combined U.S. military—Japanese Self Defense facility. As part of the 2019 dialogue, the Core Group spent their third and final day visiting Yokota Air Base, the headquarters of both United States Forces Japan and Japan Air Self Defense Force Air Defense Command.

“ “These visits allow us to better understand Alliance operational challenges in the field,” noted Eikenberry. “Just as importantly, it affords us an immediate opportunity to test out some of the very ideas discussed during the preceding days.”
