President George W Bush tried to make a quick exit from a news conference in Beijing on Sunday - only to find himself thwarted by locked doors.
After answering just six questions from a group of US reporters, the president strode away heading towards the door.
President Bush tugged at both handles on the double doors before admitting: "I was trying to escape. Obviously, it didn't work."
Mr Bush was in China in the latest stop of his East Asia tour.
The president had called the news session with US reporters at his hotel.
His earlier meeting with Chinese President Hu Jintao did not permit media questions.
Mr Bush answered a range of questions before one reporter said: "Respectfully, sir - you know we're always respectful - in your statement this morning with President Hu, you seemed a little off your game, you seemed to hurry through your statement. There was a lack of enthusiasm. Was something bothering you?"
The president answered: "Have you ever heard of jet lag? Well, good. That answers your question."
The reporter asked for a follow-up question but the president then thanked the attending journalists and said "No you may not" as he walked away.
He strode from the lectern to the door, trying both handles and then breaking into a laugh.
An aide escorted him to the correct exit and on to dinner at the Great Hall of the People.
