BEIJING (AFP) - Former National Basketball Association star Dennis Rodman returned to China from Pyongyang on Saturday after a five-day trip, where he met North Korean leader Kim Jong Un, but without jailed American Kenneth Bae.

The flamboyant former Chicago Bulls player arrived at Beijing Airport on a flight from North Korea, an AFP photographer witnessed, with a cigar clamped in his mouth.

He showed a waiting crowd of reporters dozens of pictures, some of them of him with Mr Kim, the roughly 30-year-old leader of the rogue nuclear-armed state who Rodman describes as his "friend", but quickly became angry, throwing insults before rushing to the parking lot.

"It's not my job to bring him back," he said when asked about Bae.

Earlier on Saturday, the North's official Korean Central News Agency quoted Mr Kim as saying that Rodman "might visit the DPRK (North Korea) any time and spend pleasant days".

Rodman was reported to have thanked his host for his "expression of good faith towards the Americans" and presented Mr Kim and his wife with a gift. The pair also watched a basketball game together.

There had been speculation that Rodman would try to use his budding relationship with Mr Kim to help free Bae.

"I'll be back over there. I'm going to try to get the guy out," the heavily tattooed Rodman told celebrity news website TMZ in May.

He also appealed for Bae's release on Twitter, posting: "I'm calling on the Supreme Leader of North Korea or as I call him 'Kim', to do me a solid and cut Kenneth Bae loose."

Bae, 45, was arrested in November 2012 as he entered the hardline communist state's north-eastern port city of Rason.

North Korea, which bans religious proselytising, said Bae was a Christian evangelist who brought in "inflammatory" material.

He was sentenced to 15 years' hard labour earlier this year on charges of trying to topple the North Korea regime.
