WASHINGTON (AP) — A visit by China's top diplomat, intended to show growing U.S.-China cooperation, has instead highlighted political differences, as Washington is speaking out about democracy protests gripping Hong Kong.

Foreign Minister Wang Yi met Wednesday in Washington with his counterpart John Kerry and got face time with President Barack Obama, who joined Wang's discussions with National Security Adviser Susan Rice at the White House.

The U.S. officials repeated the usual bromides about deepening ties, and they discussed Obama's Nov. 10-12 visit to China, when it hosts an economic summit of Asia-Pacific leaders.

But Kerry also spelled out U.S. support for electoral change in the Chinese territory of Hong Kong. Wang said that was none of Washington's business.
