Chinese President Xi Jinping reportedly delivered a forceful criticism of Japan’s growing military posture during his recent summit with US President Donald Trump in Beijing, highlighting rising geopolitical tensions across East Asia and growing anxieties over regional security.
According to several people familiar with the discussions, Xi became unusually vocal and visibly agitated while discussing Japan and its defense policies during the high-level meeting with Trump. The remarks reportedly targeted Japanese Prime Minister Sanae Takaichi and Tokyo’s increasing military spending, which Beijing has repeatedly characterized as a dangerous shift toward remilitarization.
Sources familiar with the summit said Xi’s comments represented one of the most heated moments during the two-day talks between the Chinese and US leaders. American officials were reportedly surprised by the intensity of Xi’s remarks because Japan had not previously featured prominently in diplomatic discussions between Washington and Beijing before the summit.
During the exchange, Xi criticized Japan’s expanding defense budget and accused Tokyo of moving away from its postwar pacifist posture. Trump responded by arguing that Japan had been forced to strengthen its security stance because of increasing threats from North Korea.
It remains unclear whether Trump directly referenced China as part of Japan’s broader security concerns during the discussion.
The confrontation underscores the growing strategic rivalry in the Asia-Pacific region, where tensions over Taiwan, military alliances, maritime disputes, and defense modernization continue to intensify.
Japan has significantly expanded its security policies in recent years amid concerns over China’s military activities near Taiwan and in the East China Sea. Tokyo has also deepened defense cooperation with countries including Australia, the Philippines, and South Korea as regional governments seek closer coordination against potential security threats.
Christopher Johnstone, a former senior White House official responsible for Japan policy, said Xi’s aggressive criticism would likely reinforce Tokyo’s push toward greater military self-reliance and stronger regional partnerships.
“Xi’s lack of self-awareness is remarkable. His own actions are accelerating the emergence of a much stronger Japan,” Johnstone said.
He added that China’s anti-Japan rhetoric has found little support outside Beijing and instead encouraged neighboring countries to strengthen security coordination in response to China’s growing assertiveness.
“Tokyo is strengthening security ties with partners across the region — including Australia, the Philippines and even South Korea — all of whom worry far more about an aggressive China than they do a ‘remilitarising’ Japan,” he said.
Japan has increasingly identified China as its primary long-term strategic challenge in official defense documents. Since 2023, Japanese defense white papers have described China’s military activities and external behavior as the country’s “greatest strategic challenge,” ranking ahead of threats from North Korea.
A draft version of Japan’s 2026 defense white paper reportedly places renewed emphasis on China’s expanding military assertiveness and growing military cooperation with Russia.
Relations between Beijing and Tokyo have deteriorated sharply in recent months, particularly after comments made by Takaichi regarding Taiwan.
In November, the Japanese prime minister said that a Chinese attack on Taiwan could pose an “existential threat” to Japan, potentially justifying military involvement under Japan’s security framework.
Although Tokyo maintained that the remarks did not represent a formal policy change, Beijing reacted strongly and accused Japan of interfering in China’s internal affairs.
Since then, China has escalated both rhetorical and economic pressure on Japan. Beijing has repeatedly criticized Tokyo’s defense expansion while also introducing restrictions on certain dual-use rare earth exports important to Japanese industries.
On Friday, China’s Foreign Ministry highlighted Japan’s increased defense spending, noting that Tokyo boosted military expenditures by nearly 10 percent in 2025.
“Japan’s defence budget has been increasing for 14 consecutive years, but Japanese right-wing forces are still clamouring for increasing defence spending,” China’s Foreign Ministry said.
“It once again shows that Japan’s ‘country for peace’ mask is coming off and it is slipping towards neo-militarism.”
The dispute comes amid broader regional military expansion across Asia.
According to data from the Stockholm International Peace Research Institute, China increased defense spending by 7.4 percent last year to approximately $336 billion, marking its 31st consecutive annual increase. Japan’s defense spending reached roughly $62 billion over the same period.
Despite the large gap between Chinese and Japanese military budgets, Beijing has continued expressing concern over Tokyo’s defense transformation and growing cooperation with Western allies.
The summit between Xi and Trump also intensified anxieties within Japan regarding the future of the US-Japan alliance.
Japanese officials have reportedly grown increasingly nervous about Washington’s long-term security commitments under Trump, particularly following disagreements over tariffs, defense obligations, and broader regional strategy.
Tokyo is also closely monitoring how the ongoing Iran conflict may affect US military resources and strategic focus in Asia.
Concerns have deepened after reports emerged that the United States informed Japan about possible delays in the delivery of 400 Tomahawk cruise missiles ordered by Tokyo in 2024.
The missiles were intended to form part of Japan’s new “counterstrike” capability designed to deter regional threats, particularly from China and North Korea.
The uncertainty surrounding Taiwan has become another major source of concern for Japan and other US allies in the region.
During the Beijing summit, Trump reportedly described a pending $14 billion US arms package for Taiwan as a useful “negotiating chip” in relations with China, sparking concern among regional partners about Washington’s commitment to Taipei’s defense.
The comments have fueled speculation about whether the Trump administration may use Taiwan-related issues as leverage in broader negotiations with Beijing.
Reports also suggest China may be delaying a potential visit by senior Pentagon official Elbridge Colby until Washington clarifies its position regarding the Taiwan arms package.
The growing tensions reflect the increasingly complex geopolitical landscape facing the United States, China, and regional allies across the Indo-Pacific.
While Washington continues seeking stable relations with Beijing, regional governments are simultaneously accelerating military preparations and strengthening security partnerships amid fears of future conflict involving Taiwan or the South China Sea.
For Japan, the latest confrontation illustrates the difficult balance Tokyo faces between maintaining its alliance with the United States, managing relations with China, and responding to rapidly evolving regional threats.
Under Takaichi’s leadership, Japan has pursued a more assertive security policy while continuing efforts to expand military capabilities and defense cooperation with democratic allies.
Meanwhile, Beijing continues portraying Japanese military normalization as a dangerous departure from the country’s postwar pacifist identity.
Neither the White House nor the Chinese embassy publicly commented on the details of Xi’s remarks during the summit.
Japan’s Prime Minister’s Office also declined to comment publicly on the reports surrounding the exchange between Xi and Trump.
Still, the reported confrontation has reinforced concerns that strategic rivalry between China and Japan could become an increasingly central issue shaping security dynamics across Asia in the years ahead.
