Spotting a large vessel off the coast of Sarawak state in March, officers on a Malaysian patrol boat were shocked when it steamed towards them at high speed, blaring its horn before veering off to reveal "Chinese Coast Guard" emblazoned on its side.

According to an officer from the Malaysian Maritime Enforcement Agency (MMEA), Chinese Coast Guard vessels have been sighted several times before around the South Luconia Shoals, off the oil-rich town of Miri. But such an aggressive encounter was a first.
