There was an interesting new post on the subject written by Cate Cadell and published at Reuters. Take a look at this excerpt:
Beijing’s propaganda campaign, which has included 11 media briefings in the capital since December, has repeatedly included efforts to discredit overseas Uighurs who speak to media.
China has also conducted overseas press events, including one this week in Canberra, released state media documentaries and a musical movie, invited diplomats from friendly countries including Iran, Malaysia and Russia to visit Xinjiang, and promoted sympathetic foreign YouTubers and news sites.
It has also targeted individual overseas think tank analysts, journalists and academics with sanctions, amplifying critical social media comments and aggressive state media coverage.
