China exported no oil, gasoline, jet fuel and diesel to North Korea in November and imported no iron ore, coal or lead from the country, Reuters reported citing data released by the General Administration of Customs on Tuesday.
The same data shows that China's exports of corn to North Korea decreased by 82 percent, comparing to a year earlier, while rice exports plunged 64 percent.
At the same time, Chinese exports of liquefied petroleum gas that is often used for cooking, rose by 58 percent from a year earlier to 99 tons, while exports of ethanol, which can be turned into a biofuel, rose by 82 percent to 3,428 cubic meters.
According Chinese Foreign Ministry spokeswoman Hua Chunying who has been asked to comment on the oil exports, "As a principle, China has consistently fully, correctly, conscientiously and strictly enforced relevant UN Security Council resolutions on North Korea. We have already established a set of effective operating mechanisms and methods."
Earlier this year, China banned coal imports from North Korea, yielding to Donald Trump's calls to increase economic pressure on the DPRK as the country is Pyongyang's biggest trade partner.
China-North Korea trade slumped this year amid several rounds of sanctions imposed by the United Nations in response to Pyongyang's multiple missile and nuclear tests.
Following the adoption of the UNSC resolution on North Korea, China called on all the parties concerned to show restraint and undertake joint efforts in order to de-escalate tensions on the peninsula.
