Trump says US may lift sanctions on Chinese companies that buy Iranian oil

US President Donald Trump said on Friday he is weighing lifting sanctions on Chinese companies that buy Iranian oil and will have a decision soon.

Trump spoke to reporters aboard Air Force One on his way back to the US after a two-day state visit to China. He also said he was okay with Iran suspending its nuclear programme for 20 years, but that there has to be a "real" commitment from Tehran.
