The China Coast Guard (CCG) has expelled two Philippine vessels for unlawfully intruding into waters near Tiexian Jiao of China's Nansha Qundao. The vessels, which attempted to illegally land on the reef and collect sand samples on Friday, have been warned and driven away, according to CCG spokesperson Liu Dejun on Saturday.

Liu reiterated that China has indisputable sovereignty over the Nansha Qundao and its surrounding waters, including Tiexian Jiao. He said the CCG will continue its law enforcement activities in waters under Chinese jurisdiction, in accordance with the law, to firmly safeguard China's territorial sovereignty and maritime rights and interests.

The incident comes amid heightened tensions in the South China Sea, where China has been increasingly assertive in its claims over disputed islands and reefs. The Philippines, along with other countries, has protested China's actions, arguing that they violate international law.

The CCG's expulsion of the Philippine vessels is the latest in a series of incidents in the South China Sea. In recent months, Chinese vessels have been accused of harassing and intimidating fishing boats from other countries, including Vietnam and Malaysia.

The United States has also expressed concern over China's actions in the South China Sea, calling on Beijing to respect international law and the rights of other countries. The US has conducted freedom of navigation operations in the region, sending warships through disputed waters to challenge China's claims.

The South China Sea is a vital waterway for global trade, and the ongoing tensions have raised concerns about the potential for conflict in the region. The international community is closely watching the situation and calling for all parties to exercise restraint and work towards a peaceful resolution.
