The U.N. Security Council on Thursday ordered tighter restrictions on North Korea's financial activities and thorough inspections of air and sea cargo headed to the country as part of stiff sanctions for conducting its third illicit nuclear test last month.
The sanctions were contained in a resolution adopted by all 15 Council members, including North Korea's top ally China.
They "will bite and bite hard" and increase Pyongyang's isolation and raise the cost to its young leader Kim Jong Un of defying the international community, U.S. envoy to the U.N. Susan Rice said.
"The entire world stands united in our commitment to the denuclearization of the Korean Peninsula and in our demand that North Korea comply with its international obligations," she said after the unanimous adoption of the resolution, according to a transcript of her remarks provided by the U.S. mission to the U.N.
The Security Council also committed Thursday to further "significant measures" if Kim conducts another nuclear or missile test.
China's U.N. Ambassador Li Baodong said Beijing wanted to see "full implementation" of the new resolution amid indications that Beijing is getting more annoyed with Pyongyang’s defiant behavior.
But Li called for a resumption of the stalled six-party aid-for-disarmament talks between the two Koreas, United States, China, Russia and Japan.
"We want to see full implementation of the resolution," Li told reporters, according to Reuters news agency. "The top priority now is to defuse the tension, bring down heat, focus on the diplomatic track."
'Pre-emptive nuclear strike'
Just before the U.N. Security Council vote, Pyongyang warned of "a pre-emptive" nuclear attack on the United States but the White House said Washington was "fully capable" of dealing with such attacks and that North Korean threats would only lead to its further international isolation.
The North's military "will exercise the right to a pre-emptive nuclear attack to destroy the strongholds of the aggressors," Pyongyang's foreign ministry warned.
A ministry spokesman said that a second Korean war was "unavoidable," as both the United States and its ally South Korea have refused Pyongyang's demands to cancel large-scale joint military exercises.
The warning came two days after Pyongyang threatened to tear apart the 1953 armistice agreement ending the Korean War.
North Korea has also launched military and civilian drills and clamped down overseas travel by both residents and officials, including to neighboring China.
The latest moves followed the launching by the United States and South Korea of a two-month field training exercise called "Foal Eagle" last week. Separately, the two allies will conduct computer-simulated drills code-named "Key Resolve" from March 11-21.
