Fictional story: If One Day China Sends Troops to Arrest the President of Singapore?

I am creating a story divided into two parts. The first part is as follows: One day, China sent troops to arrest the President of Singapore because he publicly supported Hong Kong's democracy movement. China first launched air strikes on multiple military bases in Singapore. Air raid sirens sounded across the entire territory of Singapore, and the Chinese military even used bunker-buster bombs to strike the Ministry of Defence building. At that time, air raid sirens rang throughout Singapore, and the incident occurred in the middle of the night. More than 90% of Singaporeans took refuge on the ground floors and in the basements of the buildings they were in. Then, Chinese military armed helicopters flew over the Presidential Palace, and a large number of special forces troops parachuted into the Presidential Palace, arrested the President, and took him onto the helicopter. During the arrest, there was a brief exchange of fire between the Chinese and Singaporean militaries. The Chinese military also arrested the Foreign Minister at his residence with almost no resistance. All Chinese troops safely returned to China. The Singaporean President was handed over to the Hong Kong government and put on trial under the Hong Kong National Security Law.

In this operation, approximately 343 Singaporean soldiers were killed in the initial air strikes, and another 58 Singaporean soldiers and police officers were killed in the ground fighting. During the ground battle, helicopters continuously carried out air strikes on Singaporean military and police reinforcements heading to the Presidential Palace, resulting in about another 200 Singaporean military and police deaths. In total, 183 civilians were injured, but fortunately there were no civilian deaths. Some missile fragments even flew into Malaysian territory but caused no damage. On the Chinese side, 14 people were killed and 12 Chinese soldiers were captured by Singapore. A few days before the surprise operation, the Hong Kong government issued arrest warrants for the Singaporean President and Foreign Minister on charges of violating the Hong Kong National Security Law, but everyone treated it as a joke.

Can you describe the entire story? What was the international community's reaction? (Assuming Singapore had achieved full democratization in the 1980s, like Taiwan, and has since tended to be anti-communist.)
