The charges again Ms. Meng, as far as I can tell are for actions that are not illegal in Canada, trading with Iran while US has commercial sanctions against that country.
Canada does not have such sanctions.
The USA dropped out of the treaty that traded dropping sanctions for an end to Iran's nuclear weapons programme.
She has been held, as a possible flight risk, in a Canadian jail and will in good time have the case for deportation to the USA heard by a Canadian judge using Canadian law.
Canada has extradition treaties with many countries. But we have refused extradition to countries , for example, where there is a death penalty or where the accused is unlikely to get a fair trial.
This is not about Ms. Meng. It is part of the Trump vs China dick-wagging.
