Canada

The two Michaels were both American State Department agents, with close ties to both American political parties. This is provable. One was deeply tied to the Republican party. He was the one that was active in North Korea, and helped a Republican agent, Dennis Rodman, to get an inside track with the North Korean leaders. He also worked closely with the Republican party to create back door influence with the North Koreans and the Chinese, facilitating various Republican operative visits to China. The other was a Vice President - Asian operations for International Crisis Group, a (Democratic) George Soros -influenced American State Department extension. They were both operatives for the American State Department in China. They also had Canadian passports, not American, so the Americans could not intervene. Perfect targets for the Chinese regime, in response to our Canadian government co-operating with the American State Department in their feud with Huawei.

It was absolutely not a 'random choice' that China picked the two Michaels.
