June 9, 2021 Share Analysts say a rare burst of anger from Malaysia over the flight of Chinese air force planes near its airspace and a coast guard vessel spotted in a disputed waterway indicates Beijing has crossed a line with Kuala Lumpur in its slow maritime expansion. Malaysia’s Ministry of Foreign Affairs said in a June 1 statement it would summon the Chinese ambassador over 16 People’s Liberation Army Air Force planes that flew over a Malaysian “maritime zone.” Malaysia’s air force scrambled its own jets to push China’s planes out. Days later, a Malaysian Maritime Enforcement Agency official said a Chinese coast guard ship had been seen 156 kilometers from shore, according to the Borneo Post domestic news website.
