Here is more from the South China Morning Post:
Beijing has blocked the Centre for Strategic and International Studies (CSIS) website in, after the Washington-based group released a piece criticising the country’s sanctions on a European think tank.
“It’s ironic that this piece would generate that response from China, given that the whole point was to … reduce restrictions, which is what China’s been pushing for in arguing against decoupling,” said CSIS fellow Scott Kennedy, who co-wrote the critique.
According to China Firewall Test, a monitoring site, the conservative Heritage Foundation and libertarian Cato Institute websites are blocked, while the conservative American Enterprise Institute is not.
And centrist Brookings Institution and CSIS are blocked while the progressive Centre for American Progress is not.
AEI fellow Derek Scissors said he has had articles blocked that question Chinese economic statistics, something Premier Li Keqiang did in 2007 as then-Liaoning Communist Party head citing “man-made” numbers, according to WikiLeaks.
China sanctioned the Mercator Institute for China Studies (MERICS) on March 22, and in response, CSIS scholars released a statement denouncing the sanctions, a move that apparently led China to block CSIS's website.
China's move also comes as CSIS hosted Japanese Prime Minister Yoshihide Suga for an event at the think tank.
