Secretary of State Rex Tillerson will head to Canada next week to co-host a meeting of high-level worldwide diplomats focused on expressing solidarity against 's ongoing nuclear weapons and ballistic missile provocations.
"At the same time", he added, "we will continue the ongoing dialogue with all partners, including countries like Russian Federation and China who absolutely will play an important role in moving towards peace on the Korean peninsula".
A Japanese foreign ministry official, meanwhile, was quoted by Bloomberg News on Wednesday raising questions about the involvement of countries such as Colombia and Greece, which are peripheral to the North Korea crisis.
But Mills would not say whether China had been invited to the Vancouver meeting and declined to provide a list of countries that had received invitations, saying a list of participating states "will be released in due time".
The Vancouver waterfront may seem like a curious locale to plot such strategy but academic Roland Paris said Canada is doing Tillerson a favour by helping showcase global solidarity for the pressure campaign.
"We all know that the worldwide community is playing an extremely important role in defusing, de-escalating tensions on the Korean peninsula", Trudeau said.
Lu said countries should work to defuse tensions and promote dialogue, rather than isolating Pyongyang.
Washington plans to use the meeting on Tuesday, January 16, to discuss the idea of stopping and inspecting suspect ships bound for North Korea, a senior official said.
After North Korea tested its most powerful nuclear device yet and launched missiles capable of reaching the US, the UN Security Council imposed a series of sanctions restricting oil imports and cutting off about 90 percent of its export revenue.
Responding to such concerns on Thursday, Brian Hook, the director of policy planning within the U.S. State Department, said the meeting is focused on United Nations sending states only, but key regional players like neighbours China and Russian Federation are being kept apprised.
North Korea was also not invited and would first have to indicate a willingness to put down its nuclear weapons before being asked to join any such meeting, Steve Goldstein, undersecretary of state for public diplomacy and public affairs, told the same briefing.
"China is working with us".
Asked whether the USA and North Korea could hold talks during the Olympics, Hook said, "No". "This ministerial will enhance and strengthen all of the efforts underway to achieve our policy goals".
