Trump, who has been very critical of Obama's foreign policies, also criticised the Philippines President for his abusive remarks against the US President.
"China wouldn't provide a red carpet stairway from Air Force One and then Philippines President calls Obama 'the son of a whore'. Terrible!" Trump tweeted this morning.
When Obama arrived for the G20 summit in Hangzhou, China over the weekend, he was not provided with a staircase to exit his plane.
