Despite a widely confirmed suspension of rare earth shipments from China to Japan, now nearly a month old, Beijing has continued to deny that any embargo exists.

Industry executives and analysts have interpreted that official denial as a way to wield an undeclared trade weapon without creating a policy trail that could make it easier for other countries to bring a case against China at the World Trade Organization.

So far, China seems to be taking a similar approach in expanding the embargo to the West.

Wang Baodong, a spokesman for the Chinese Embassy in Washington, said on Tuesday that the Chinese government was putting new restrictions on the mining, processing and export of rare earths to protect the environment. But he said that China was not violating any W.T.O. rules in doing so and that it was not imposing an embargo or trying to use rare earths as a bargaining chip.

"With stricter export mechanism gradually in place, outbound shipments to other countries might understandably begin to feel the effect," Mr. Wang said in an e-mail. "But I don't see any link between China's reasonable rare earth export control policy and the irrational U.S. decision of protectionist nature to investigate China's clean energy industries."

Nefeterius Akeli McPherson, a spokeswoman for the Office of the United States Trade Representative in Washington, said that American trade officials were looking into the matter, after a report of the Chinese customs restrictions was published on Tuesday afternoon on the Web site of The New York Times.

"We've seen the news report and are seeking more information in keeping with our recent announcement of an investigation into whether China's actions and policies are consistent with W.T.O. rules."

Jeremie Waterman, the China director of the United States Chamber of Commerce, said that he was still checking government and industry sources to learn the extent of a suspension of Chinese rare earth shipments. "If it's true, it's disturbing news to say the least," he said.

Western and Japanese leaders can protest all they want but they might as well join hands and sing Kumbayah, because China has demonstrated the way most important wars will be fought in future. Military forays in Vietnam, Afghanistan and Iraq have reminded the world that conventional wars are hugely expensive in blood and treasure, often to little effect.

Welcome to the commodity wars, long forecast by Fullermoney, which break few laws and take few lives, while securing the most important treasure that money can buy.
