Since Mr. Biden took office, the United States has denied the company some, but not all, of the types of key chips needed for its equipment — leading the company on a drive for self-sufficiency. And there is evidence that, by starving the company, it has begun to sharply curtail Huawei’s profitability and much of its influence.
For its part, the Chinese government has underwritten the cost of installing Huawei gear, in an effort to dominate networks from Latin America to the Middle East.
Ms. Meng came to personify that effort. Her determination to wire up Tehran, at a time in which the West was seeking to contain Iran’s nuclear program, attracted protests among American officials. For that reason, some China hard-liners objected on Friday to news that the charges were being dropped.
“It sends the wrong message to Chinese business executives around the world that it’s permissible to engage in fraudulent transactions with Iran and North Korea,” said Michael Pillsbury, a scholar at the Hudson Institute who was a top China adviser to former President Donald J. Trump. “I fear that another part of the message has been that the Biden team approved selling Huawei some types of chips and technology, which will also undercut the message that Huawei should not be involved in 5G telecommunications systems of our friends and allies.”
Huawei mustered a furious effort in Washington and in Canada to get Ms. Meng released. But she refused to plead guilty to bank and wire fraud charges stemming from Huawei’s deal in Iran. Months later, she agreed to a deferred prosecution agreement, which will ultimately lead to dropping all the charges against her.
The case began when Canadian authorities arrested Ms. Meng, 49, in December 2018, at the request of the United States. She owns two imposing homes in Vancouver, and was allowed to stay in them with an ankle bracelet to track her whereabouts. She eventually settled at her gated, seven-bedroom mansion in the city’s exclusive Shaughnessy neighborhood, where she received painting lessons and private massages.
She instantly became one of the world’s most famous detainees — especially because she is the daughter of Huawei’s famous founder and chief executive, Ren Zhengfei, a former People’s Liberation Army officer who turned his small telecommunications firm into a national champion.
