Indonesian President, Joko Widodo has said, there will be no compromise to his country's sovereignty in the contested South China Sea. The comments come after Australia's foreign minister, Julie Bishop, on Tuesday said the two countries were considering joint naval patrols in the contested waters. Indonesian warplanes staged a large-scale exercise last month in the waters around the Natuna Islands archipelago, following a spate of face-offs between the country's navy and Chinese fishing boats in the gas-rich southern end of the South China Sea.<br/><br/>Meanwhile, China has said, the two countries had overlapping claims to waters close to them, an area Indonesia calls the Natuna Sea. China claims almost the entire South China Sea. Brunei, Malaysia, the Philippines, Taiwan, Vietnam and Indonesia also claim part of the sea.
