In a recent statement, the US State Department has criticized China for allegedly using environmental pretexts to assert territorial claims over the South China Sea, a critical maritime region. The US condemned China's attempts to establish a 'nature reserve' around the Scarborough Reef, near Luzon island, which it claimed would deny Filipino fishermen access to their traditional fishing grounds. The US contends that this move is merely an attempt by Beijing to bolster its territorial ambitions in the region. The statement also expressed concern over China's refusal to participate in arbitration panels and its assertion of the 'nine-dash line', a controversial border claim that encompasses much of the South China Sea. Tensions have escalated recently, with Chinese ships reportedly using water cannon against Filipino fishing vessels near the Scarborough Shoal. Both countries have long disputed sovereignty over the area. The US reaffirmed its support for the Philippines and a free and open Indo-Pacific region, citing ongoing territorial disputes as an opportunity to strengthen its strategic position in Asia. In April, the US held joint military exercises with Canada and Australia in the region, further underscoring its commitment to regional security. US Secretary of State Marco Rubio has also condemned China's aggressive actions in the South China Sea, calling out the use of water cannon against Filipino vessels as disturbing.
