Earlier, China said on the 25th that an American U-2 high-altitude reconnaissance plane broke into the no-fly zone of live-fire exercises in the northern theater of the People's Liberation Army without authorization, and China demanded that the United States immediately stop provocation.

According to the South China Morning Post, the People's Liberation Army launched two missiles toward the South China Sea on Wednesday morning, including one Dongfeng -26B missile launched from Qinghai and the Dongfeng -21D missile launched from Zhejiang.

Sources said that both missiles were launched toward the sea area between Hainan Province and Xisha Islands.

On the 21st, Hainan Maritime Safety Administration announced that it would conduct military training activities in the southeast waters of Hainan Island from 24th to 29th, and both missiles fell into the exercise forbidden zone. According to sources, the purpose of China's missile launch this time is to strengthen China's ability to refuse other forces to enter the South China Sea.

The source also analyzed that "US military aircraft and warships are entering the South China Sea more and more frequently, and China's move is in response to the potential risks brought by US actions". "China doesn't want neighboring countries to misunderstand Beijing's purpose".

Song Zhongping, a Hong Kong military commentator, said that China's missile launch was obviously sending a signal to the United States. He said that the United States continued to test China's bottom line on Taiwan and South China Sea issues, and urged China to show its military strength, so as to let the United States know that even American ships could not show their full strength in China's coastal waters.

According to sources, China's Ministry of National Defense did not immediately respond to this comment.
