The President made the comments Saturday as he met with British Prime Minister Theresa May at the G20 meeting in Hamburg, Germany, confirming that the two countries are now working on a trade agreement.
The value of May's offer was further brought into question when the White House made clear that, despite previous suggestions from Trump and United Kingdom supporters of Brexit, Britain would, in fact, be left behind the European Union when it came to settling any future trade deals.
"There is no country that possibly be closer than our countries", he said.
"I think we'll have that done very, very quickly", he said.
Later, in response to an entreaty by Indonesian President Joko Widodo, Trump said he'd also like to visit that country.
There are tensions over trade, migration and climate change, after Mr Trump announced the U.S. would pull out of the Paris Climate Change Accord.
Christopher Meyer, a former British ambassador to Washington, said Trump's statement of intent was a "very good sign for the future" and would be "useful" to May.
In a 30-minute meeting on the margins of the G20 with China's President Xi Jinping, she urged Beijing to stop flooding the market with cheap steel imports, calling for "more activity" to reduce over-capacity; the UK's steel industry has been devastated by a wave of cheap Chinese steel.
May was the first leader to officially visit Trump, but the prime minister faced a barrage of criticism upon her return by MPs who questioned whether Britain should develop such a close relationship with the controversial leader.
Trump's pledge came during a working session of the G20 summit of world leaders in Hamburg, providing a "godsend" to the UN World Food Programme, the group's executive director, David Beasley, told Reuters on the sidelines of the meeting.
The BBC's diplomatic correspondent James Robbins, in Hamburg, said this was exactly the sort of signal that the prime minister would have been looking for. We either be "very timid" and sit back or we can be bold and that is what we are going to be.
The President also said he had had a "tremendous meeting" with his Russian counterpart, in his first comments on his talks with Vladimir Putin on Friday, which lasted more than two hours.
Mrs May is also holding one-to-one talks with Turkish president Recep Tayyip Erdogan to discuss ways to tackle the increasing numbers of Islamic State fighters leaving Syria across its border.
