Taiwan Arms Sales After Trump's China Visit —

📡 THE SIGNAL — What Happened

Why it matters: The possibility of President Trump approving a large-scale arms sale to Taiwan immediately after his visit to China indicates that US-China relations have entered a new era driven by "transactions" rather than "principles." This is a structural shift directly impacting the stability of the Taiwan Strait, the alliance structure in the Indo-Pacific, and Japan's security environment.

• Diplomacy — Reuters reported on March 14, 2026, that President Trump may approve a large-scale arms sale to Taiwan after his visit to China.
• Diplomatic Schedule — President Trump is scheduled to make an official visit to China from late March 2026.
• China's Stance — President Xi Jinping cautioned the US side regarding arms sales to Taiwan, stating they should be "handled carefully."
• Scale of Arms Sale — The report described it as a "large-scale arms sale," suggesting it could exceed previous sales packages (billions of dollars).
• Historical Context — The US has continued to provide defensive arms to Taiwan based on the Taiwan Relations Act (1979).
• Military Balance — The Chinese People's Liberation Army has normalized military exercises around Taiwan in recent years, shifting the military balance in the Taiwan Strait towards China.
• Political Background — The Trump administration has pursued "transactional diplomacy," treating trade negotiations and security issues with China as a package.
• Industry — Major US defense industry players such as Lockheed Martin and Raytheon are key contractors for arms supply to Taiwan.
• Taiwan Politics — Taiwan's Lai Ching-te administration is considering raising defense spending to over 3% of GDP.
• Regional Security — Indo-Pacific nations such as Japan, Australia, and the Philippines have direct interests in the stability of the Taiwan Strait.
• Economy — Taiwan is a linchpin of the global semiconductor supply chain, centered around TSMC, and military tensions directly translate into economic risks.
• Diplomatic Approach — The timing of approving the sale "after" the China visit is a calculation to maintain deterrence while somewhat accommodating Xi Jinping's "face."

The issue of arms sales to Taiwan has remained the most sensitive fault line in US-China relations since the normalization of diplomatic ties in 1979. To understand this issue, it is necessary to review the structural evolution of the US-China-Taiwan triangular relationship over half a century.

In 1979, when the Carter administration recognized the People's Republic of China and severed diplomatic relations with Taiwan (Republic of China), the US Congress enacted the Taiwan Relations Act. This law legally guarantees the US commitment to Taiwan's security, explicitly stating that the US will "provide Taiwan with such defense articles and defense services as may be necessary to enable Taiwan to maintain a sufficient self-defense capability." In 1982, the Reagan administration issued the "August 17 Communiqué" with China, promising to "gradually reduce" arms sales to Taiwan in both "quality and quantity." However, at the same time, Reagan conveyed the secret "Six Assurances" to Taiwan, pledging not to set a termination date for arms sales. This dual structure—official consideration for China and unofficial assurances to Taiwan—has been the essence of US Taiwan policy for over 40 years.

After the end of the Cold War, the Taiwan issue entered a new phase. During the 1995-96 Taiwan Strait Crisis, China reacted to Taiwanese President Lee Teng-hui's visit to the US by conducting missile exercises, to which the US responded by deploying two aircraft carriers. This crisis once again demonstrated the explosive potential of the Taiwan issue in US-China relations. Subsequently, the George W. Bush administration approved a large-scale arms sales package to Taiwan in 2001 (including submarines, anti-submarine patrol aircraft, and Kidd-class destroyers), and the Obama administration also carried out sales in 2010 and 2011. In all cases, China vehemently protested and took retaliatory measures such as temporarily suspending military exchanges, but it did not lead to a fundamental breakdown in US-China relations.

During Trump's first term (2017-2021), a qualitative change occurred in Taiwan policy. Before his inauguration, Trump held a phone call with President Tsai Ing-wen (the first direct call between US and Taiwanese leaders since 1979) and subsequently approved multiple arms sales to Taiwan. However, what is noteworthy is the anecdote where Trump likened the Taiwan issue to the "tip of a pen" and mainland China to a "desk." This symbolizes a transactional worldview that regards Taiwan as a "card" in negotiations with China.

In Trump's second term, as of 2026, this transactional approach has become even more pronounced. The Trump administration is simultaneously negotiating multiple issues with China, including reducing the trade deficit, curbing fentanyl inflow, and the North Korean issue, and arms sales to Taiwan are positioned as one element of this negotiation package. The calculation of approving the sale "after" the China visit suggests several strategic intentions. First, there is a calculation to extract concrete "results"—for example, trade concessions or promises of stricter fentanyl regulations—during direct talks with Xi Jinping during the visit, and then implement the arms sale, thereby containing China's backlash within the context of "results already obtained." Second, as a political consideration for anti-China hardliners within the US (Republican conservatives, the Taiwan lobby, and the defense industry), there is a need to send a message that Taiwan has "not been sold out to China."

However, this framework has a fundamental problem. Treating Taiwan's security as a subject of "transaction" structurally undermines the credibility of US commitments to its allies and partners. Japan, South Korea, the Philippines, Australia, and others will be forced to factor in the possibility that their own security might be sacrificed in the US's "next deal." This is the core of the "alliance fissures" dynamic, a structural change that will ripple across the entire Indo-Pacific security order.

At the same time, for China's Xi Jinping administration, this development is not simple. Engaging in a "transaction" with Trump creates a contradiction with its principled stance on the Taiwan issue (no concessions on core interests). However, unification with Taiwan by force entails enormous military and economic costs and is not a realistic option. As a result, cross-strait relations are heading towards chronic tension, characterized by gradually increasing military pressure and normalized diplomatic deterrence, all under the guise of "maintaining the status quo."

The delta: By intentionally linking Trump's visit to China with the Taiwan arms sale, the Trump administration has entered a new phase where Taiwan's security is openly treated as a "bargaining chip" between the US and China. This represents a qualitative shift from traditional "strategic ambiguity" to "strategic transactionalism," a structural change that creates fissures in the credibility of alliance structures across the entire Indo-Pacific.
