With the media assembled as Donald Trump speaks at the business event in Doha, he's covering a lot of topics, APA reports citing Sky News.
The US president now turns to Iran, and says he thinks the US is getting very close to a nuclear deal with the country.
He explains that Iran has "sort of" agreed to the terms, and goes on to say they can't have a nuclear weapon.
"We're not going to be making any nuclear dust," he says.
"It's very simple," Trump adds, before adding that he wants them to succeed.
It comes after reports that a top Iranian official has said the country is prepared to make a number of concessions related to its nuclear programme in exchange for the lifting of economic sanctions.
Ali Shamkhani, a top political, military and nuclear adviser to Iranian Supreme Leader Ayatollah Ali Khamenei, spoke to Sky News' US partner NBC News.
He said Tehran was willing to commit to never making nuclear weapons again, getting rid of its stockpiles of highly enriched uranium, which can be weaponised, agree to only enrich uranium to the lower levels needed for civilian use and allow international inspectors to supervise the process.
This was in exchange for the prospect of the immediate lifting of all economic sanctions on the country.
