(Recasts throughout with details of Chinese bans, background on tensions between United States and North Korea)
SHANGHAI, Sept 23 (Reuters) - China said on Saturday it will ban exports of some petroleum products to North Korea, as well as imports of textiles from the isolated North, in line with a United Nations Security Council resolution passed after Pyongyang’s latest nuclear test.
The announcement from Beijing came at the end of a week that saw tensions ratchet up between the United States and North Korea, with the leaders of both countries trading insults.
The Ministry of Commerce said in a statement on its website that China would limit exports of refined petroleum products from Oct. 1 and ban exports of condensates and liquefied natural gas immediately to comply with the latest U.N. sanctions.
Imports of textiles from North Korea would also be banned immediately, the statement said.
Textile trade contracts signed before Sept. 11 would be respected if import formalities are completed before midnight on Dec. 10, the statement said.
The moves follow the adoption of a unanimous UN Security Council agreement on sanctions after the isolated North conducted its sixth and most powerful nuclear test on Sept. 3.
That resolution imposed a ban on condensates and natural gas liquids, a cap of 2 million barrels a year on refined petroleum products and a cap on crude oil exports to North Korea at current levels.
Russia urged calm on Friday after U.S. President Donald Trump called North Korean leader Kim Jong Un a “madman”. Kim had called Trump a “mentally deranged U.S. dotard” a day earlier after Trump said Washington would “totally destroy” North Korea if it threatened the United States or its allies.
Trump announced new U.S. sanctions on Thursday that he said allows the targeting of companies and institutions that finance and facilitate trade with North Korea. U.S. Treasury Secretary Steven Mnuchin also said banks doing business in North Korea would not be allowed to operate in the United States.
China has also urged calm, with Foreign Minister Wang Yi telling his Japanese counterpart that Tokyo should not abandon dialogue over North Korea.
North Korea has launched dozens of missiles this year, several of them flying over Japan, as it accelerates a weapons programme aimed at enabling it to target the United States with a nuclear-tipped missile.
The United States and South Korea are technically still at war with North Korea because the 1950-53 Korean conflict ended with a truce and not a peace treaty.
The North accuses the United States, which has 28,500 troops in South Korea, of planning to invade and regularly threatens to destroy it and its Asian allies. (Reporting by Andrew Galbraith; Editing by Paul Tait)
