China Lodges Formal Complaint Over Japan's 2026 Defence White Paper
The Facts
- Japan released its annual defence white paper, "Defense of Japan 2026," on Tuesday, Aug. 4; the document runs roughly 600 pages, was approved by the Cabinet, and is the first such assessment under Prime Minister Sanae Takaichi, with a prologue by Defence Minister Shinjiro Koizumi.
- The white paper identifies China as Japan's greatest strategic challenge, describing Beijing's military activities as an unprecedented challenge and a matter of serious concern for Japan and the international community.
- The paper states that China has intensified its military activities around Taiwan and that the "overall military balance between China and Taiwan is rapidly tilting in China's favour."
- The document presents defence spending as beneficial to the broader Japanese economy, calling for greater use of commercial components, funding for startups and expanded dual-use technology between the defence and civilian sectors.
- Chinese Defence Ministry spokesman Chen Xi said the paper is "filled with false narratives," exaggerates a regional security crisis and hypes the so-called "China threat" as a pretext for removing constraints on Japan's own military development, adding that China expressed "strong dissatisfaction and firm opposition."
- Chinese Foreign Ministry spokesman Lin Jian said on Wednesday that Beijing had lodged serious representations with Tokyo, and that Japan has no right to comment on Taiwan because it is purely China's internal affair.
- Beijing urged the international community to stay on alert and push back against what it described as Japan's accelerating military expansion, which it called a factor threatening regional peace and stability.
- Beyond China, the white paper assesses threats from North Korea's nuclear and missile programmes and from Russia, and Koizumi wrote that Japan's security environment is as severe and complex as at any time since the end of World War II.

What is Japan's defence white paper?
It is the Japanese Defence Ministry's annual public assessment of the country's security environment, including the military capabilities and activities of neighbours China, Russia and North Korea El Economista,China Daily. The 2026 edition runs about 600 pages, was compiled over roughly a year by civilian and military experts at the ministry and Self-Defence Forces, and was approved by the Cabinet before release El Español,Anadolu Ajansı,Global Time….
Why is Taiwan at the centre of the dispute?
Beijing claims Taiwan as its own territory, a claim Taipei rejects Reuters. The white paper says China has intensified military activity around the island, seeks to "create a fait accompli" through exercises, and could blockade Taiwan using coast guard vessels Taiwan News. China's foreign ministry responded that resolving the Taiwan question "is a matter for the Chinese people themselves and brooks no interference" from outside, and that Tokyo has no standing to comment Reuters,Japan Today.
What happens next, and what is the wider context?
Japan is drafting a new national security strategy that could include further increases in military spending, with analysts expecting much of it directed at deterrence related to a potential Taiwan contingency Ambito. Relations between Tokyo and Beijing have deteriorated, and Chinese officials note Japan has accelerated revisions of its main security documents and raised its defence budget Ambito,S A N A.

Where Left and Right agree, and where they split
- Where Left and Right agree
- The white paper does two things at once — names China, North Korea and Russia as threats and argues defence spending benefits the economy — and neither reading disputes either half.
- Where Left and Right split
- A threat claim arriving bundled with a spending pitch that deserves separate scrutiny, or Beijing telling a sovereign government it may not describe the Taiwan balance aloud.
How left and right read it
Notice that this threat assessment doubles as an economic case: alongside naming China the greatest strategic challenge, it pitches defence spending as good for the broader economy, with startup funding and expanded dual-use technology. When the argument for public money and the argument for danger arrive in the same document, each deserves scrutiny on its own terms. With both capitals now accusing the other of manufacturing crisis, insist that security be measured by risk reduced, not budgets grown.
A roughly 600-page assessment, approved by Japan's Cabinet, with Defence Minister Shinjiro Koizumi writing that the security environment is as severe as at any point since World War II — and naming North Korea and Russia alongside China. That is a sovereign government doing its own accounting. Beijing's claim that Tokyo has no right to comment on Taiwan is the tell: when the military balance across the strait is tilting rapidly one way, who exactly is entitled to say so out loud?
