The arrest of Huawei's chief financial officer Meng Wanzhou in Canada at the request of the US has ramped up the tension and rancour between Washington and Beijing. It is also forcing a reckoning about the role of Chinese money in America.

Members of the Twitterverse have begun to point out that certain US think-tanks have accepted money from Huawei, which the US government considers to be linked to China's intelligence apparatus. Yet they are not the only research institutions that need to think seriously about their relationship with China these days - American universities have their own dilemmas to consider.
