Taiwanese Presidential Shooting - continued

This last bit from a CNN story didn't sit well with me:

On Saturday, Taiwan holds presidential elections and a controversial referendum that China considers a harbinger for a vote on the island's independence.

The referendum will ask voters to considern if China should reduce its military threat against the island.

Chen has ignored warnings from Washington and Beijing not to take any steps that could fuel tensions with mainland China.

Does Washington not want a Taiwanese President that continues to press for independence?
