Chinese Ambassador to Canada Cong Peiwu has denounced the United States as a "trouble maker" in the China-Canada relationship, two weeks after a judge in Vancouver rejected a bid by Huawei executive Meng Wanzhou to have her U.S. extradition case thrown out.

Eighteen months ago, Meng – Huawei's chief financial officer and the daughter of the company's founder Ren Zhengfei – was arrested at Vancouver International Airport by Canadian police on a U.S. warrant. Washington has accused her of fraud linked to the alleged violation of U.S. sanctions against Iran and wanted her to face trial in New York. Meng has denied any wrongdoing.

She was released on bail by a British Columbia court days after. But since then, she has worn a GPS ankle bracelet and been subject to 24-hour supervision by a private security firm at her Vancouver home with her husband.

What's behind Trump's fear of Huawei?

CGTN's interview with Chief Security Officer for Huawei America: Attacks on Huawei more about politics than security

Huawei is one of the top 5G suppliers in the world, helping more than 90 countries build cutting-edge, next-generation mobile networks. The company is also the second-largest phone maker after Samsung and holds more than 40 percent of the Chinese market.

After it was drawn into the trade dispute between the world's two largest economies last May and put on the entity list, the Trump administration doubled down on sanctions, with new rules issued on May 15. That makes it mandatory to have a government license for selling Huawei semiconductors manufactured out of the country with U.S. technology.

"This is a grave political incident plotted by the United States to bring down Chinese hi-tech companies," Ambassador Cong told Reuters in a telephone interview on Thursday when asked for comment on Meng's case. "The U.S. has been taking advantage of Canada." 

U.S. President Donald Trump said in December 2018 that he would intervene with the Justice Department in Meng's case if that would help secure a trade deal with Beijing. "(Her arrest) was a political incident rather than a simple judicial case," the Chinese envoy added.
