China Review News published a commentary on August 31, 2010, titled "The U.S. Is the Black Hand Stopping Normal Cross-Strait Military Communications." According to the article, the fact that retired Taiwanese high-ranking military officials have frequently visited Mainland China in recent years has attracted much U.S. attention. The United States has expressed its concerns through Taiwan’s representative in the U.S., Yuan Jiansheng, and wanted Taiwan to provide an explanation.
“As we understand it, the largest third hand (interfering with) cross-strait military relations is the United States. … Therefore, calling the U.S. a black hand is not wrong.”
