China flexes blockade capabilities near Taiwan on second day of military drills

The maneuvers increased tension around the Taiwan Strait as 2025 drew to a close, but the impact extended beyond military pressure into everyday life. Taiwan’s Civil Aviation Administration was notified that seven temporary “dangerous zones” had been set up around the strait, affecting international and domestic air travelers. It was not immediately clear whether that involved flight cancellations as opposed to delays.

Xinhua, China's official news agency, posted a commentary late Monday saying the drills sent an unequivocal message: That Beijing is always ready to prevent anything that tries to split Taiwan from China. Each escalation, it said, would be met with stronger countermeasures.

“By currying favor with the United States through obsequious loyalty gestures and promoting arms purchases, the DPP is binding the entire island of Taiwan to its catastrophic secessionist chariot, disregarding public opinion,” it wrote, referring to Taiwan’s ruling Democratic Progressive Party.

130 aircraft and a Chinese balloon detected

Taiwan's Defense Ministry said it had detected 130 aircraft, including fighters and bombers, 14 military ships and eight other official ships around the island between 6 a.m. Monday and 6 a.m. Tuesday. Its forces kept monitoring the development and deployed aircraft, navy ships and coastal missile systems in response. Ninety of the Chinese aircraft crossed the median line of the strait and entered Taiwan's “air defense identification zone.” A Chinese balloon was also spotted, it said.

It said the PLA long-range artillery unit in Fujian, a southeastern Chinese province, fired live rounds toward a target zone north of the island, with impact zones scattered around the line, 44 kilometers (27 miles) off its coast.

Taiwan's Defense Minister Wellington Koo said the Chinese troops’ actions were highly provocative, undermined regional stability and posed security threats and disruptions to passing ships, trade activities and flight routes.

While Beijing sends warplanes and navy vessels toward the island on a near-daily basis, the scale of these exercises escalated tensions between both sides. China claims the island off its southeastern coast as sovereign territory and has vowed to seize it, by force if necessary.

Chinese Defense Ministry spokesperson Zhang Xiaogang said the drills served as a stern warning to “Taiwan independence” separatist forces and external forces, without naming any countries.

He criticized Taiwanese President Lai Ching-te 's administration for what it called pandering to external forces and pursuing independence, saying that was the root cause of disrupting the status quo in the strait and escalating tensions.

Last week, Beijing imposed sanctions against 20 defense-related U.S. companies and 10 executives, following a Washington announcement of large-scale arms sales to Taiwan valued at more than $10 billion. Those sales still require approval by the U.S. Congress.

Under U.S. law, Washington is obligated to assist Taipei with its defense, a point that has become increasingly contentious with China over the years.

Trump not worried

On Monday, U.S. President Donald Trump said that while he was not informed of the military exercise in advance, neither was he particularly worried about it. He touted his “great relationship” with Chinese President Xi Jinping and suggested he didn’t think Xi was going to attack Taiwan.

The Taiwan issue also heightened China-Japan tensions. Beijing has expressed anger at a statement by Japan’s prime minister, Sanae Takaichi, saying its military could get involved if China takes action against the democratically ruled island. There remains widespread overall suspicion in China about Japan that goes back generations to when imperial Japan brutally took over parts of China in the years before World War II.

China and Taiwan have been governed separately since 1949, when the Communist Party rose to power in Beijing following a civil war. Defeated Nationalist Party forces fled to Taiwan, which later transitioned from martial law to multiparty democracy.

Facing the drills, Taiwan on Monday called the Chinese government “the biggest destroyer of peace.” It cautioned carrying live-fire exercises around the strait could bring more complex challenges to the international community and neighboring countries.

Stoking the tensions, China's Eastern Theater Command posted a series of online images and videos carrying provocative language throughout the exercises. In one video titled “So Near, So Beautiful — Anytime to Taipei," it showed its footage of Taipei 101, a landmark of Taiwan's capital city.
