After the faction-change and Sino-Soviet split, the US actually sold weapons to PRC. It lasted until 1989 where the Tiananmen Square protest ended it all with a PR disaster.

Ironically PRC has more Black Hawk helicopters than Taiwan: http://en.wikipedia.org/wiki/UH-60_Black_Hawk#Military_opera...

Also not sure if anyone noticed some of the choppers during the parade were Eurocopter Dauphins. http://en.wikipedia.org/wiki/Eurocopter_Dauphin
