Bolton Asks China to support U.N. on North Korean

The U.S. ambassador to the United Nations prodded a reluctant China on Sunday to aggressively implement a U.N. weapons ban on North Korea, declaring that Beijing has a "heavy responsibility" to influence its longtime ally.

Speaking one day after the U.N. Security Council imposed sanctions, John Bolton said on ABC's "This Week" that it would be "powerfully persuasive in Pyongyang," the North Korean capital, if the regime's leading supplier of energy and food took tough action to halt weapons traffic in and out of the North.

"China has got a heavy responsibility here," said Bolton, adding that North Korea's nuclear test last Monday "had to have been humiliating to China," which has urged patient diplomacy to halt Pyongyang's nuclear program.
