Really not sure if you're joking or not, but Meng Wanzhou (https://en.wikipedia.org/wiki/Meng_Wanzhou) was a major turning point for China-US and China-Canada relations.
She was detained in Vancouver on the request of the US DoJ and held in house arrest for three years - after which they dropped all the charges and let her go back to China. She was absolutely used as a bargaining chip by the US government.
>>...under the indictment of bank and wire fraud regarding financial transactions in violation of U.S. sanctions against Iran by Skycom, which had functioned as Huawei's Iran-based subsidiary. On 24 September 2021, the DOJ announced it had reached a plea bargain with Meng to resolve the case through a deferred prosecution agreement...
The charges were dismissed. Her “plea bargain” had her deny all the key charges and simply admit to one false statement - which did not amount to any criminal wrongdoing.
> The Department of Justice said it would move to dismiss all the charges against Meng when the deferral period ends on 21 December 2022…
> On 1 December 2022, the prosecution asked a judge to dismiss bank fraud and other charges against her,[58] and the judge dismissed the charges.[17]
Since when has this ever happened? In China, yes. In the US, never!
How foolish of them. China can only look in the mirror with this.
