BEIJING — China is defending its export curbs on rare earth minerals used in high-tech products as an environmental measure and rejected a World Trade Organization challenge by the United States, Europe and Japan.
A Cabinet official rejected complaints last week that China is using the environment as an excuse to support fledgling Chinese producers of lightweight magnets and other rare earths products by limiting supplies to foreign rivals in violation of its free trade pledges.
“The protection of the environment is never a pretext for gaining advantage or increasing economic returns,” said Su Bo, a deputy industry minister, at a news conference.
China has about 30 percent of rare earth mineral deposits but accounts for more than 90 percent of production. The Chinese government alarmed global manufacturers by imposing export quotas in 2009. It is trying to build up domestic manufacturers to capture more of the profits that now go to U.S., Japanese and European companies that transform rare earths into mobile phone batteries, camera lenses and other products.
In March, the U.S., European Union and Japan filed World Trade Organization complaints accusing China of violating its commitments to the global free-trade body.They say export limits push up the price of rare earths abroad, giving buyers in China an unfair advantage.
Officials held talks April 25-26 in the first step of the WTO dispute-resolution process, said another official, Gao Yun, deputy director-general of the industry ministry’s rare earths office.Gao gave no details of the talks.
If no resolution is reached after 60 days, the dispute can be sent to a WTO panel for a ruling. Depending on the outcome, sanctions against China are possible.
“All these measures fully conform to WTO rules,” Gao said. He said China wants a quick resolution but said it will “actively use world trade rules” to protect its companies.
The dispute reflects the clash between China’s free trade pledges and its ambitions to transform China from a low-wage factory into a creator of profitable technology by building up and protecting its fledgling high tech companies.
Rare earths are 17 minerals used to make goods that include hybrid cars, weapons, flat-screen televisions, mobile phones, mercury-vapor lights and camera lenses.
China has announced an export quota of 10,546 tons of rare earths for the first half of this year. That is down 27 percent from the quota set for the same period a year ago.
The government said last year’s total exports were 18,600 tons, just 60 percent of the 30,000-ton quota, due in part to slack global demand.
The United States, Canada, Australia and other countries also have rare earths but most mining stopped in the 1990s as lower-cost Chinese ores came on the market.
China’s decision to limit exports has prompted foreign producers to announce plans to reopen or develop mines in California, Canada, India, Russia and elsewhere.
On Tuesday, Australian miner Lynas Corp. announced it hopes to start up a rare earths processing plant in Malaysia after a parliamentary panel ruled it is safe. The facility in the northern state of Pahang has faced opposition from residents on environmental grounds.
Su said China hopes other countries “take their fair share of responsibility” for ensuring supplies by encouraging development of rare earths mines.
China also hopes the export controls will encourage foreign rare earths companies to shift operations to China, providing investment and technology. Su said 38 U.S., Japanese and other companies have set up joint ventures or wholly-owned entities in China and he appealed for more foreign investment in environmental protection and processing.
Besides export quotas, China has further tightened controls by limiting the number of companies licensed to sell abroad.
Chinese controls have helped to push global rare earths prices far above what buyers in China pay. One mineral, terbium oxide, cost about $909 per pound on world markets this week and $443 in China, according to Lynas. Another, dysprosium oxide, cost $468 per pound abroad and $300 in China.
Last October, a state-owned company that is China’s biggest rare earths announced a one month suspension of production in an effort to shore up slumping prices.
Despite such measures, Su insisted the government has never tried to manipulate prices.
“The price of an international product such as rare earths is determined purely by supply and demand,” he said.
