China’s state news agency says background checks on all its nationals on board the missing Malaysian jetliner have uncovered no links to terrorism. Xinhua said the Chinese ambassador to Malaysia made the statement on Tuesday to media in Kuala Lumpur.

There has been some speculation that Uighur separatists in far western Xinjiang province might have been involved with the flight’s disappearance.

Xinhua also reported that Chinese authorities have begun searching for the plane on Chinese territory.

There were 154 Chinese among the 227 passengers aboard on Flight 370, which went missing March 8 on its way to Beijing.
