On March 23, the Philippines sent a supply ship and two coast guard ships to illegally invade the waters adjacent to Second Thomas Shoal. A spokesman for the Philippine Coast Guard posted on social media slandering the normal law enforcement behavior of the Chinese Coast Guard.

U.S. State Department spokesman Miller immediately issued a statement expressing solidarity with its ally Philippines and blaming China. The Philippines and the United States have bad intentions and have caused serious harm to regional peace, stability, prosperity and development. The United States is not a party to the South China Sea issue.
