BEIJING (AP) — China warned Canada on Friday that it needs to be aware of the consequences of aiding the U.S. in an extradition case involving Chinese tech giant Huawei that is believed to have sparked the detentions of two Canadians in China.

Foreign ministry spokesman Geng Shuang's comments came after U.S. Vice President Mike Pence and Canadian Prime Minister Justin Trudeau called for the release of Michael Kovrig and Michael Spavor.

Both were arrested on Dec. 10 after Canada detained a Huawei executive wanted by the United States on fraud charges. While China has denied they were taken in retaliation, it has repeatedly implied that there is a strong connection between the cases.

Korvig, a former diplomat and Asia expert at the International Crisis Group, and Spavor, a businessman, have been accused of colluding to steal state secrets. Canada has repeatedly urged their immediate release, calling their detentions arbitrary. Neither has been permitted access to lawyers or family members.

"We hope that the Canadian side can have a clear understanding of the consequences of endangering itself for the gains of the U.S. and take immediate actions to correct its mistakes so as to spare itself the suffering from growing damage," Geng said at a daily news briefing.

Huawei CFO Meng Wanzhou, the daughter of the company's founder, is accused of lying to banks about the company's dealings with Iran in violation of U.S. trade sanctions. Her attorney has argued that comments by U.S. President Donald Trump suggest the case against her is politically motivated.

Washington has pressured other countries to limit the use of Huawei's technology, warning they could be opening themselves up to surveillance and theft of information.

China and the U.S. are currently embroiled in a trade dispute that is weighing heavily on global financial markets.

Another Canadian held in China, Robert Schellenberg, was re-sentenced to death in a drug case following Meng's detention. His case is currently under appeal.
