North Korea called the latest U.N. sanctions “an act of war” that violates its sovereignty, and said it is a “pipe dream” for the United States to think it will give up its nuclear weapons.

The U.N. Security Council unanimously approved tough new sanctions against North Korea on Friday in response to its latest launch of a ballistic missile that Pyongyang says can reach anywhere on the U.S. mainland. The resolution was drafted by the United States and negotiated with the North’s closest ally, China.

“We define this ‘sanctions resolution’ rigged up by the U.S. and its followers as a grave infringement upon the sovereignty of our Republic, as an act of war violating peace and stability in the Korean peninsula and the region and categorically reject the ’resolution,’” North Korea’s foreign ministry said in a statement.

The ministry said the sanctions are tantamount to a “complete economic blockade” of North Korea.

“If the U.S. wishes to live safely, it must abandon its hostile policy towards the DPRK and learn to co-exist with the country that has nuclear weapons and should wake up from its pipe dream of our country giving up nuclear weapons which we have developed and completed through all kinds of hardships,” said the statement, carried by the North’s official Korean Central News Agency.

DPRK is short for North Korea’s official name, the Democratic People’s Republic of Korea.

The resolution adopted by the Security Council includes sharply lower limits on North Korea’s refined oil imports, the return home of all North Koreans working overseas within 24 months, and a crackdown on ships smuggling banned items including coal and oil to and from the country.

The Trump administration’s success in achieving the resolution won praise from the top Democrat on the Senate Foreign Relations Committee, Ben Cardin of Maryland. “That was a good move,” the senator said, “a major accomplishment.” Cardin said the stepped-up sanctions should be followed by diplomacy aimed at bringing the U.S. and China together on a sustained effort to ease tensions in that region. Cardin spoke on “Fox News Sunday.”

But the resolution doesn’t include even harsher measures sought by the Trump administration that would ban all oil imports and freeze international assets of the government and its leader, Kim Jong Un.
