UNITED NATIONS: China and Russia are pushing the UN Security Council to lift some sanctions on North Korea to ease the country's humanitarian concerns and to "break the deadlock" in stalled denuclearisation talks between Washington and Pyongyang, China's UN ambassador said on Tuesday.

On Monday, China and Russia proposed the 15-member council lift a ban on North Korea exporting statues, seafood and textiles, and ease restrictions on infrastructure projects and North Koreans working overseas, according to a draft resolution seen by Reuters.

"With regard to the sanctions, that's also something DPRK has concerns (with) and their concerns are legitimate," China's UN ambassador, Zhang Jun, told reporters, referring to the Democratic People's Republic of Korea.

"If you want them to do something you need to accommodate their concerns. That's the logic behind China and Russia's initiative."

Asked when the draft resolution could be put to a vote, Zhang said: "Once we feel we have strong support then we will take further action."

Council diplomats met on Tuesday to discuss the draft text. A resolution needs nine votes in favor and no vetoes by the United States, France, Britain, Russia or China to pass.

US Ambassador to the United Nations Kelly Craft posted on Twitter on Tuesday: "The @UN Security Council has and should always speak in unison on North Korea. We are willing to consider united action, but it must advance the commitments @POTUS Trump and Chairman Kim made in Singapore."

North Korean leader Kim Jong Un and President Donald Trump met for the first time in Singapore in June 2018 and have met twice more since, but no progress toward denuclearisation has been made and Kim has given Trump until the end of 2019 to show flexibility.

North Korea's UN envoy declared this month, however, that denuclearisation was off the table.

The United States, Britain and France have insisted that no UN sanctions should be lifted until North Korea takes concrete steps to give up its nuclear and ballistic missile programs. Pyongyang has been subject to UN sanctions because of those programs since 2006.

A US State Department official said on Monday that now was not the time to consider lifting UN sanctions on North Korea as the country was "threatening to conduct an escalated provocation, refusing to meet to discuss denuclearisation, and continuing to maintain and advance its prohibited weapons of mass destruction and ballistic missile programs."

The sanctions on industries that Russia and China have proposed lifting earned North Korea hundreds of millions of dollars and were put in place in 2016 and 2017 to try to cut off funding for Pyongyang's nuclear and missile programs.

"What we are going to do is not to further split the Security Council, but to pursue a united approach in obtaining peace and security there," Zhang said.

"The core goal is to send a constructive, positive message to the parties concerned that we do not want a deteriorated situation, we do not want a confrontation, we do encourage them to go forward instead," he said.

China hopes the Security Council can speak with one voice on the issue and reach consensus on the draft resolution, Chinese Foreign Ministry spokesman Geng Shuang told a media briefing earlier on Tuesday.

Concerns were growing internationally that North Korea could resume nuclear or long-range missile testing - suspended since 2017 - because denuclearisation talks between Pyongyang and Washington have stalled.
