Michael Kovrig

China's government and its leading smartphone maker, Huawei Technologies Ltd, stepped up pressure on Monday on the U.S. and Canadian governments in a dispute over trade and telecoms technology that has ensnared Huawei's CFO, who faces U.S. criminal charges.

Former Canadian diplomat Michael Kovrig, being held in China on suspicion of endangering national security, is not entitled to diplomatic immunity, China's foreign ministry said on Monday.

China confirmed Thursday two Canadians are under investigation on suspicion of endangering the country's national security, fuelling tensions after Canada's arrest of a top Chinese telecom executive on a US request.

A second Canadian citizen who has been questioned by authorities in China is "presently missing", Canadian officials said Thursday, adding to tensions following the arrest of a top Chinese telecom executive on a US request in Vancouver.

A Canadian, believed to be a former diplomat, has been detained in China, prompting concern in Ottawa and Washington, as Beijing fumes over the arrest of a senior technology executive.
