In a speech marking the 105th anniversary of the Chinese Communist Party on July 1, 2026, Xi Jinping did not mince words on Taiwan. China must “resolutely strike Taiwan independence separatist forces,” he told the Great Hall of the People in Beijing, vowing to “firmly advance the great cause of national reunification” and defeat “external interference” — language analysts read as directed squarely at the United States and Japan.
He also doubled down on military modernisation, declaring that the People’s Liberation Army must “advance national defense and military modernization to a high level” in time for the centenary of the PLA’s founding next August 2027. That single phrase — military readiness, timed to 2027 — sits at the heart of the most consequential debate in Indo-Pacific security strategy: what, exactly, is China preparing to do?
The concept has a name. The “Davidson Window” refers to the period between 2021 and 2027 during which military analysts believe China could develop sufficient capabilities to attempt control of Taiwan.
It takes its name from Admiral Philip Davidson, then-commander of the U.S. Indo-Pacific Command, who warned Congress in 2021 that Xi Jinping had instructed the PLA to be ready to conduct an invasion of Taiwan by 2027, according to USNI News.

But the Davidson Window was always a readiness benchmark, not a declaration of intent — and the distinction has become increasingly important as 2027 approaches.
Former CIA Director William Burns, who cited the 2027 readiness order publicly, immediately qualified it: the instruction to be prepared “does not mean he’s decided to invade in 2027 or any other year,” Burns said, as reported by USNI News.
A U.S. intelligence assessment released in March 2026 went further, concluding that China currently has no fixed timetable for reunification and does not plan to invade Taiwan in 2027, according to USNI News.
Xi himself has pushed back against the narrative. At a summit near San Francisco in November 2023, when the subject came up, Xi reportedly grew exasperated — not at the risk of war, but at the timeline. “I hear all these reports in the United States of how we’re planning for military action in 2027 or 2035,” Xi said, according to a U.S. official who later spoke to the press, as reported by Defense News. “There are no such plans,” he said.

Three converging clocks explain why 2027 remains the central planning horizon. The first is military: it marks the 100th anniversary of the PLA’s founding in 1927, a milestone Xi has explicitly tied to modernisation goals. The second clock is political: 2027 precedes the 21st National Congress of the Chinese Communist Party, where Xi is widely expected to seek another term, as noted by BreezyScroll.
The third clock is structural: 2027 also marks the point at which the U.S. Navy will have contracted from 292 ships in 2022 to approximately 280, while China’s fleet continues its expansion. China has nearly tripled its precision-attack missiles to 3,500 systems since 2020.
That military build-up is not in dispute. “All indications point to the PLA meeting President Xi Jinping’s directive to be ready to invade Taiwan by 2027,” said Admiral John Aquilino, Adm. Davidson’s successor as INDOPACOM commander, in congressional testimony at the end of his tenure.
Tensions have also been coloured by the Trump factor. Trump has claimed at various points that Xi assured him China would not attack Taiwan during his presidency — an assurance Beijing has not publicly confirmed, according to BreezyScroll.

The two leaders met in Beijing in May 2026, according to CNBC’s reporting on Xi’s July speech, and Xi is scheduled to visit the U.S. in September. Trump’s occasional mixed signals on whether America would militarily intervene in a Taiwan contingency have been viewed by some analysts as creating strategic ambiguity — and by others as dangerous confusion. The U.S. has continued approving arms sales to Taiwan throughout.
Xi’s 2026 anniversary speech marked a notably outward-looking departure from previous CCP anniversary addresses, which typically focused on domestic “national rejuvenation,” according to CNBC.
His framing of China as a party that has “deeply changed the trend and trajectory of the world’s development” — combined with the sharpened Taiwan language and the explicit military readiness call — was read by analysts in Tokyo as a warning directed specifically at Japan, following Prime Minister Takaichi Sanae’s remarks in November 2025 that Japan would intervene in a Taiwan contingency, according to the Yomiuri Shimbun.
China has since added 40 Japanese institutions and companies to its export restrictions on dual-use items including rare earths.
