U.S. President Joe Biden said Monday he decided to extend U.S. sanctions on North Korea for another year, a move that follows the latest U.S. outreach to the reclusive nation for dialogue at any time and place.

In a letter to the speaker of the U.S. House of Representatives, Biden said the North's fissile material as well as its pursuit of nuclear and missile programs "continue to constitute an unusual and extraordinary threat to the national security, foreign policy, and economy of the United States."

"For this reason, I have determined that it is necessary to continue the national emergency declared in Executive Order 13466 with respect to North Korea," he said in the letter, released by the White House.

The executive order declaring a national emergency with respect to North Korea first went into effect on June 26, 2008, under the George W. Bush administration.
