SEOUL: Chinese planemaker COMAC has opened an office in Singapore, China's embassy in the country said, as the state-owned company tries to break into a global passenger jet market dominated by Western manufacturers. The new Asia-Pacific office was a key symbolic step for the passenger jet maker in taking its aircraft overseas, China's ambassador to Singapore, Cao Zhongming, said at the inauguration. "It's hoped that COMAC will make steady progress on the road of internationalisation," he added,
