The Civil Aviation Administration of China (CAAC) recently sent a letter to 36 international air carriers demanding that they remove from their websites references implying that Taiwan, Hong Kong, and Macau are not part of China. The letter comes just months after Beijing punished and chastised companies like Marriott, Zara, and Delta for not showing enough deference to Beijing’s views of territorial integrity. 

(Comment: China is using new propaganda and psywar methods of enforcing its territorial claims. These harness its economic strength as bargaining chips.)
