Theresa May will meet Donald Trump for one-on-one talks when she travels to the G20 in Hamburg this weekend, Downing Street has confirmed.
The Prime Minister and President are expected to use the bi-lateral talks to discuss the situation in North Korea, whose government has just successfully tested an intercontinental ballistic missile.
Ms May will also raise the Paris climate agreement with Mr Trump, who believes the treaty should be renegotiated to make it more favourable to the US.
She is expected to say the UK sees no need for negotiation – though Downing Street has yet to explicitly and definitively rule out changes.
Mr Trump has accepted the PM's invitation to visit the United Kingdom on a state visit but details of the trip – including a date – have yet to be confirmed.
It was reported that Mr Trump might make a "flying visit" to London with just 24 hours notice in order to stymie mass demonstrations against his presence in Britain.
A senior UK government official said: “The PM and the President are expected to discuss the latest missile test by North Korea.
“We are in agreement with the US Secretary of State Rex Tillerson that ‘global action is required to stop a global threat’.
“The PM will say it is essential the international community is united in condemnation of North Korea’s actions.
“Our focus is on working with the US and international community on how we can increase pressure and find a peaceful solution to the ongoing threat North Korea poses to international security.
“We will continue to play a central role at the UN - supporting resolutions on sanctions that will limit North Korea’s ability to pursue its nuclear weapons programme.
“The Prime Minister is also expected to raise climate change with the President, stressing that the UK remains fully committed to the Paris Agreement.
“She will say that we don't see any need for renegotiation - we support the Paris Agreement because it delivers.”
