As I think I mentioned in response to one of your colleagues, we're working very closely with IRCC and CBSA to make sure that they're aware of the recent change in the situation in China.
With regard to other countries, there have been a number of very high-profile what they call “refoulements” from countries in which Uighurs were seeking refugee status, for example, Thailand, Malaysia and Turkey. That situation dates from about 2015 to 2016. Various governments have taken various measures. In the case of Thailand, they sent a rather large group back to China. It's complicated in Thailand, because Thailand isn't a signatory to the convention on refugees.
But yes, a number of countries have deported Uighurs back to China, something that I think is probably very problematic under the current situation in the country.
