Japan becomes contested variable after summit

Donald Trump’s May 14 summit with Xi Jinping in Beijing is being read by analysts less as a reset than as a clearer map of where U.S.-China tensions now sit. The immediate headlines focused on trade, tariffs and Taiwan, but reporting after the meeting showed Xi also used the encounter to press Trump on Japan’s military buildup. That matters because it puts Japan more explicitly inside the strategic conversation between Washington and Beijing, rather than on the sidelines of it. INSS analysts Galia Lavi and Eldad Shavit wrote on May 24 that the meeting produced “many statements” and “few breakthroughs,” while Bloomberg, citing the Financial Times, reported that Xi became unusually heated when discussing Japan. ### Why did Japan emerge from a U.S.-China summit about more than trade? Xi Jinping used the Beijing meeting not only to address bilateral U.S.-China disputes but also to draw attention to what Beijing sees as shifting security conditions in East Asia. Bloomberg’s May 24 report, citing the Financial Times, said Xi criticized Japanese Prime Minister Sanae Takaichi’s rearmament push during the summit and that U.S. officials were caught off guard because Japan had not featured prominently in pre-summit bilateral preparations. (inss.org.il) The INSS analysis published on May 24 said Beijing went into the summit seeking recognition of its status as an equal great power while setting boundaries around what it considers core interests. In that framework, Japan’s defense posture is not a separate file. It sits alongside Taiwan and alliance politics as part of China’s wider argument about U.S. power in Asia. That is an analytical reading by named authors, not a formal Chinese statement, but it fits the way the summit was described afterward. (bloomberg.com) ### Why would Beijing connect Japan, Taiwan and U.S.-China rivalry? Taiwan was already central to the summit before Trump arrived in Beijing. Bloomberg reported on May 11 that Trump said he would discuss U.S. arms sales to Taiwan with Xi, and on May 15 it reported Trump later said he had made “no commitment either way” to Xi on the issue. Those exchanges placed Taiwan at the center of the meeting’s security dimension from the outset. (inss.org.il) Japan enters that picture because Tokyo’s defense buildup changes how China assesses the regional balance around any Taiwan contingency. Japan’s government has publicly anchored that buildup in the National Security Strategy, National Defense Strategy and Defense Buildup Program adopted in December 2022. Japan’s foreign ministry says those plans include stronger defense capabilities, including counterstrike capabilities, and a broader reinforcement of the country’s security architecture. (bloomberg.com) ### What exactly is Beijing objecting to when it says “remilitarisation”? The phrase reported by the Financial Times and echoed by Bloomberg points to China’s longstanding opposition to Japan expanding military roles and spending. What is newer is not the complaint itself but the venue: Xi raised it directly with the U.S. president during a summit meant to stabilize the two biggest economies’ relationship. Bloomberg said several people described Xi’s criticism of Japan as the most heated part of the meeting. (mofa.go.jp) Japan’s own documents describe the changes in different terms. The foreign ministry says the 2022 strategy package was adopted in response to a deteriorating security environment and frames it as reinforcement of national defense within Japan’s constitutional order. That leaves a clear gap between Tokyo’s justification and Beijing’s characterization. ### So what changed after this summit? The clearest shift is in emphasis. (bloomberg.com) The INSS paper said the summit did not deliver major breakthroughs, but it did clarify each side’s priorities and red lines. If Xi chose to elevate Japan in a meeting with Trump, that suggests Beijing wants Washington to view Japanese defense policy as part of the broader U.S.-China dispute, not as a separate alliance-management issue. That conclusion is an inference from the summit reporting and the INSS analysis, rather than a declared joint position. (mofa.go.jp) The next concrete markers will come from the same three tracks that surfaced in Beijing: U.S. decisions on Taiwan arms sales, Chinese messaging on regional security, and Japan’s implementation of the defense buildup plans adopted in December 2022. Japan’s foreign ministry continues to present those plans as the governing framework for its security policy, while post-summit reporting suggests Beijing now wants them treated as a live issue in U.S.-China diplomacy.
