Taipei [Taiwan], Taiwan's Ministry of National Defense (MND) said 23 Chinese military aircraft and five Chinese warships operated around Taiwan from 6 a.m. (local time) on Friday to 6 a.m. (local time) on Saturday.

Of these, 20 Chinese military aircraft entered the Air Defense Identification Zone (ADIZ) of northern, central, southwestern and eastern Taiwan, according to Taiwan's MND. In response to China's action, Taiwan's military has monitored the situation and responded accordingly.

Since September 2020, China has stepped up its use of gray zone tactics by increasing the number of military aircraft and warships operating near Taiwan.

According to a Taiwan News report, gray zone tactics are "an effort or series of efforts beyond deterrence and ensuring a stable state that attempts to achieve security objectives without resorting to direct and considerable use of force".

This latest incident adds to a series of similar provocations by China in recent months. China has increased its military activities around Taiwan, including regular air and naval raids on Taiwan's Air Defense Identification Zone (ADIZ).

Taiwan has long been a contentious issue in China's foreign policy. China continues to assert its sovereignty over Taiwan and considers it part of its territory and insists on eventual reunification, by force if necessary.

Meanwhile, Taiwan has advised its citizens not to travel to China, Hong Kong and Macau following threats from Beijing to execute supporters of Taiwanese independence.

Liang Wen-chieh, spokesperson for Taiwan's Mainland Affairs Council, issued the warning in response to rising tensions with China, which considers Taiwan part of its territory and has refused to engage with Taiwan's government since the election of President Tsai Ing-wen in 2016.

The advisory aims to warn Taiwanese travelers about potential risks under China's new guidelines aimed at supporters of Taiwanese independence. While travel is not prohibited, citizens are discouraged from expressing political opinions or engaging in activities that could lead to arrest or prosecution by Chinese authorities.

Previously, Taiwan had criticized Beijing's threat to impose harsh punishments, including the death penalty, on those who support Taiwanese independence. A notice issued by Beijing specified the death penalty for leaders of independence efforts who cause serious harm to the state and people, while other prominent defenders could face prison terms ranging from 10 years to life in prison.

Taipei condemned the new Chinese guidelines, saying Beijing lacks legal jurisdiction over Taiwan and dismissing the regulations as not binding on Taiwanese citizens.

In a press release, the Mainland Affairs Council (MAC) criticized the guidelines previously announced by Chinese officials as "regrettable," calling them provocative and detrimental to interactions between the people of Taiwan and mainland China.

China's growing pressure on Taiwan independence supporters stems from its long-standing claim that Taiwan is part of its territory, despite the island's self-rule since 1949.
