A Canadian judge on Wednesday altered the bail terms of a Chinese tech executive facing possible extradition to the United States on fraud charges, granting her lawyers’ request that she be allowed to move from a $6 million, six-bedroom house in Vancouver to a $16 million, seven-bedroom mansion in the city’s exclusive Shaughnessy neighborhood.

Lawyers for the executive, Meng Wanzhou, the chief financial officer of the Chinese tech giant Huawei, requested the change at a hearing before the Supreme Court of British Columbia. The courtroom was filled to capacity, a reflection of the intense interest in the case since Ms. Meng was arrested in December by Canadian officials in Vancouver.

Her arrest put Canada in the center of a diplomatic struggle between China and the United States, which sought her arrest and is seeking her extradition. The United States has since accused Ms. Meng of, among other things, fraudulently deceiving four banks to enable Huawei to evade American sanctions against Iran.

Ms. Meng’s arrest has also created a rift between China and Canada. China has detained — in retaliation, some say — two Canadians and accused them of espionage, and it has sentenced two other Canadians to death on drug-related accusations.
