China will pay the biggest price from the new United Nations sanctions against North Korea because of its close economic relationship with the country, but will always enforce the resolutions, Chinese Foreign Minister Wang Yi said.

The United Nations Security Council unanimously imposed new sanctions on North Korea on Saturday that could slash its $3 billion in annual export revenues by about one-third.

Speaking at a regional security forum in Manila on Monday, Wang said the new resolution shows China and the international community's opposition to North Korea's continued missile tests, the Foreign Ministry said in a statement Tuesday.
