Communist China's aircraft forced Canadian planes to divert from their flight paths, Canada’s military stated.

Diplomatic tensions between China and Canada are rising again, with each country accusing the other of using their military aircraft flying near North Korea of provocation and harassment.

Earlier on Monday, Bejing’s regime foreign ministry warned Canada of potential “severe consequences” of any “risky provocation,” after Canada’s military last week accused Chinese warplanes of harassing its patrol aircraft monitoring North Korea’s compliance with sanctions.

The U.N. Security Council has never authorized any country to carry out military surveillance in the seas and airspace of other countries in the name of enforcing sanctions, foreign ministry spokesman Zhao Lijian said at a media briefing, avoiding to add that NATO has performed such missions since 1952.

Canadian Prime Minister Justin Trudeau, speaking to reporters in Ottawa, responded that Canadian planes were participating in a U.N. mission.

Communist China’s actions “are irresponsible and provocative” and “are putting people at risk, while at the same time not respecting decisions by the U.N. to enforce U.N. sanctions on North Korea,” Mr. Trudeau said.
