The United States last week accused China of raising tensions in the South China Sea by its apparent deployment of surface-to-air missiles on a disputed island, a move China has neither confirmed nor denied.
Asked whether the South China Sea, and the missiles, would come up when Wang is in the United States to meet Secretary of State John Kerry, Foreign Ministry spokeswoman Hua Chunying said Washington should not use the issue of military facilities on the islands as a "pretext to make a fuss".
"The U.S. is not involved in the South China Sea dispute, and this is not and should not become a problem between China and the United States," Hua told a daily news briefing.
China hopes the U.S. abides by its promises not to take sides in the dispute and stop "hyping up" the issue and tensions, especially over China's "limited" military positions there, she said.
"China's deploying necessary, limited defensive facilities on its own territory is not substantively different from the United States defending Hawaii," Hua added.
U.S. ships and aircraft carrying out frequent, close-in patrols and surveillance in recent years is what has increased regional tensions, she said.
"It's this that is the biggest cause of the militarization of the South China Sea. We hope that the United States does not confuse right and wrong on this issue or practice double standards."
