NEW DELHI, Aug 4 (Reuters) - India is sending a naval task force to the South China Sea this month to expand security ties with friendly countries, officials said on Wednesday, signalling its intent to play a bigger role in regional efforts to counter China. The Indian military has been traditionally wary of antagonising China but the mood has hardened following clashes between troops on the disputed land border last year. The government has since drawn closer to the United States in efforts to push back against China. Four ships including a guided missile destroyer and a missile frigate will be deployed for a two-month period to southeast Asia, the South China Sea and the western Pacific, the navy said in a statement. "The deployment of the Indian Navy ships seeks to underscore the operational reach, peaceful presence and solidarity with friendly countries towards ensuring good order in the maritime domain..." the navy said. The South China Sea has become one of many flashpoints in the testy relationship between China and the United States, with Washington rejecting what it calls unlawful territorial claims by Beijing in the resource-rich waters. In June, a U.S. aircraft carrier group led by the USS Ronald Reagan entered the South China Sea as part of a routine mission and a British carrier group is due to undertake exercises in the Philippine Sea this month. As part of their deployment, the Indian ships will take part in annual joint war drills involving the United States, Japan and Australia off the coast of Guam, the navy said. The four countries make up the Quad, an informal group, that U.S. President Joe Biden"s administration is promoting as a way to counter an assertive China. "These maritime initiatives enhance synergy and coordination between the Indian Navy and friendly countries, based on common maritime interests and commitment towards Freedom of Navigation at sea," the Indian navy said in its statement. China has in the past criticised multilateral military manoeuvres as destabilising to the region.
