The United States, Europe and Japan have joined forces to challenge China's restrictions on exports of rare-earth metals, escalating a trade row over access to some of the most important raw materials used in advanced technologies.

In a formal complaint to the World Trade Organization (WTO), the three trade powers accused Beijing of trying to hold down prices for its domestic manufacturers and to pressure international firms to move operations to China.

We want our companies building those products right here in America. But to do that, American manufacturers need to have access to rare earth materials which China supplies, U.S. President Barack Obama said at the White House.

Europe's trade chief said China's restrictions violated international trade rules and had to be removed.

These measures hurt our producers and consumers in the EU and across the world, including manufacturers of pioneering hi-tech and 'green' business applications, said European Union Trade Commissioner Karel De Gucht.

Rare earths are crucial for the defense, electronics and renewable-energy industries and are used in a range of products such as the iPhone, disk drives and wind turbines.

China described the trade complaint on Wednesday as unfair, arguing that it only controlled 90 percent of global production because other countries, notably the United States, had long ago closed their own rare earths refineries on pollution concerns.

The irrational exploitation of rare earth in China had led to underestimation of the values of rare earth, state news agency Xinhua said in a commentary, adding that pollution from rare earths refining had forced it to curb production.

It is strange that the Western world has never launched 'anti-dumping' measures against China's rare earth products as they have, more often than not, done to other China-made products such as shoes, shirts and tires.

China has said its export curbs aim to both control environmental problems and preserve supplies of an exhaustible natural resource. Refining rare earths requires large amounts of acid, and also produces low-level radioactive waste.

Beijing set an export quota of 33,353.7 tons in 2011, but it shipped only 18,586 tons last year, official data shows. The squeeze has led to a fourfold increase in export prices over the past two years, encouraging buyers to shift operations to China and also develop non-rare earth technologies.

China's Minister of Industry and Information Technology Miao Wei said China was preparing to defend itself in the WTO.


What are rare earths:

Rare earths resources



Investors bought shares in Chinese rare earth miners and Japanese rare earth processors on Wednesday, hoping the WTO action would force Beijing to allow more exports.

Higher export quota potentially will allow them to sell more to overseas customers which are paying a high price for rare earth, said Felix Fok, analyst at research firm JI Asia.

Hong Kong-listed China Rare Earth Holdings jumped 10 percent on Wednesday. In Japan, rare earth processor Alconix rose 4.4 percent, and in Australia rare earth miners also climbed as the spotlight returned to a sector that had been struggling.

Some of these rare earths stocks have been absolutely smashed, said Shaun Giacomo of Petras Capital in Sydney. Of the Australian listed miners, Alkane Resources rose 11 percent and Araufura Resources 9.5 percent.


Obama, who has faced criticism from Republican rivals for not being tough enough with Beijing, has hardened his stance on Chinese trade practices as he gears up for a re-election battle.

Our competitors should be on notice. They will not get away with skirting the rules, Obama said.

The rare earths dispute, which has been building for years, comes as China undergoes a political transition, with Vice President Xi Jinping poised to become the leader of the world's second-largest economy by early 2013.

The United States and Europe have clashed regularly with China over economic issues including the value of the Chinese currency. The United States is due to make a preliminary decision next week on whether to impose countervailing duties on Chinese-made solar panels, potentially adding to trade tensions.

The rare earths case is the first to be jointly filed by the European Union, the United States and Japan.

Though dependent on the outside world for vast qualities of industrial components such as iron and coal, China accounts for about 97 percent of world output of the 17 rare earth metals.

China continues to make its export restraints more restrictive, resulting in massive distortions and harmful disruptions in supply chains for these materials throughout the global marketplace, said U.S. Trade Representative Ron Kirk.


The action over China's export curbs involving rare earths, as well as tungsten and molybdenum, begins a 60-day process for the two sides to try to resolve the dispute.

The next step would be for the United States, the EU and Japan to ask the WTO to establish a dispute-settlement panel to decide the case. Once appeals are lodged and heard, the process could take as long as two years to complete.

The EU, the United States and Mexico won a similar case against China in January concerning other raw materials. A European official close to the case said China had not removed wider export restrictions since that ruling. In particular, the EU said in a statement, rare earth quota announcements are further tightening the restrictions and are a clear signal in the wrong direction.

Beijing has until the end of March to tell the United States, the EU and Mexico how it intends to comply with the January ruling, providing an opportunity for China to address both that case and the rare earth restrictions at the same time, Kirk said in an interview.

We are hopeful that because the WTO ruling in the raw materials case was so unequivocal that China will work with us, Kirk said.

Foreign companies pay up to twice as much as Chinese firms for rare earth metals, the EU said.

The EU directly imports 350 million euros worth of rare earths from China each year, and also brings in products of far greater value containing rare earths from Japan and elsewhere.

The damage done to European manufacturing runs into billions of euros, the official said, because it was nearly impossible to diversify away from Chinese supply.
