Earlier on Monday, China's Foreign Ministry warned Canada of the potential "severe consequences" of any "risky provocation", after the Canadian military last week accused Chinese warplanes of harassing its patrol planes tasked with monitoring North Korea's compliance with sanctions."The UN Security Council has never authorized any country to carry out military surveillance in the seas and airspace of other countries in the name of sanctions enforcement," the spokesman said. Foreign Ministry Zhao Lijian at a press briefing.Canadian Prime Minister Justin Trudeau, speaking to reporters in Ottawa, replied that the Canadian planes were taking part in a UN mission.China's actions "are irresponsible and provocative" and "put people at risk, while failing to respect UN decisions to apply UN sanctions against North Korea," Mr. Trudeau.Last week, Trudeau was more measured, calling the harassment of Canadian warplanes "extremely disturbing."Chinese planes have sometimes forced Canadian planes to deviate from their flight path, the Canadian military said last week.Defense Ministry spokesman Wu Qian said the Chinese military took reasonable steps to address Canada's actions and made "solemn representations" through diplomatic channels.China's defense ministry said in a statement that Canadian warplanes have stepped up reconnaissance and "provocations" against China "under the pretext" of implementing UN Security Council resolutions, putting endangering China's national security.The rise in tensions between Canada and China follows Ottawa's decision last month to ban the use of 5G equipment from Chinese company Huawei Technologies Co. on national security grounds.That move was delayed after Canada detained Huawei executive Meng Wanzhou in 2018 on behalf of the United States and Beijing subsequently arrested two Canadians on spying charges.That standoff ended when the three were released in September after US prosecutors reached a settlement with Meng.
