Hostage diplomacy worked for China

... The Huawei exec who's been under house arrest in Vancouver for a couple years on request by America (they said she bypassed their embargo on Iran, I think, and wanted her deported to the US. She's been arguing against deportation from Canada since then).

Shortly after the exec's detention, China detained two Canadians, saying they were spying. (It sounds like they were never charged, just detained until now).

Shortly after the exec recently made a deal with the US and was released by Canada to return to China, China released the two Canadian men.

"Because it was so blatently a form of hostage diplomacy I think people are going to start thinking about how they deal with China. ... a major emerging power that doesn't really follow international law, so there's a lot of implications that need to be addressed." - Clifford Coonan
