Washington: US President Barack Obama has issued an executive order imposing new sanctions on North Korea, the media has reported.
The White House on Wednesday announced that the "robust new sanctions" are part of its response to the 6 January nuclear test and 7 February ballistic missile launch conducted by North Korea, Xinhua reported.
The executive order blocks certain transactions on properties belonging to the North Korean government and to the ruling Workers' Party of Korea.
The US Department of the Treasury also announced new sanctions on Pyongyang following Obama's executive order. The sanctions are aimed at 17 government officials and organisations. It also identified "20 vessels as blocked property".
The new sanctions target North Korea's energy, mining, financial services and transportation sectors, prohibit exports of goods, services, technology and new investment in the country.
"These actions are consistent with our longstanding commitments to apply sustained pressure on the North Korean regime," the White House said, adding, "The US and the global community will not tolerate North Korea's illicit nuclear and ballistic missile activities."
Earlier this month, the UN Security Council unanimously adopted a resolution on tougher sanctions on North Korea to curb the country's nuclear and missile programmes. The Security Council members also called for an early resumption of the Six-Party Talks.
The Six-Party Talks, a mechanism involving North Korea, South Korea, China, Japan, US and Russia, is believed to be a practical way to realise denuclearisation on the Korean Peninsula.
It was launched in 2003 but stalled in December 2008. Pyongyang quit the talks in April 2009.
