Do you know Japan and China are not going well

China has blocked all exports of rare earths to JaPAN, STEPPING up the pressure on Tokyo to release a Chinese boat captain detained in disputed waters, a repot said thursday.
China has halted all shipments to Japan of the chemical elements essential for the making of mp3 players. electric cars, missiles and a range of other products, the New York Times reported, citing unnamed industry sources.
Calls to China's commerce and foreign ministries for comment on the report went unanswered.
Japan's foreign ministry and the world's top automaker Toyota -- one of many companies that would be affected by the move -- also did not answer calls.
Japan and China are embroiled in their worst diplomatic row in years, sparked by the captain'

Chinese premier wen Jiabao this week threatened "further action" if the captain was not released. Beijing has already suspended high-level contacts with Tokyo and called off several official visits.

China supplies at least 95 percent of the world's rare earths. It had preveiously cut its export limit for the minerals, sending market prices soaring and sparking concerns among foreign governments and comapnies.

previous media reports said the country was considering even banning the export of certain elements and closing mines, which foreign companies and governments fear will deny them access to the much-needed metals and force manufacturers to shift their plants to China.
