China briefly cut off crucial oil supplies to North Korea recently in an apparent bid to rein in its unpredictable neighbor after Pyongyang test-fired missiles, diplomats said on Monday.



It was the first sign of Beijing appearing willing to use its economic muscle to twist arms in Pyongyang after months of criticism from Washington for failing to do enough to pressure North Korea to curb its nuclear ambitions.

Talk of Chinese pressure on its longtime ally came as a South Korean envoy, national security adviser Ra Jong-yil, headed to Russia and China to restart stalled efforts on a diplomatic resolution to the crisis.

China cited technical problems for the three-day shutdown in March of an oil pipeline running from its northeastern province of Liaoning to North Korea, but the message was clear: behave, a Western diplomat said.

"It was cut for three days after the second missile," the diplomat quoted Chinese sources as saying, referring to North Korea firing a cruise missile into the Sea of Japan on March 10, Pyongyang's second missile test in two weeks.

"The tough message was: get straight," the diplomat told Reuters.
