Iranian President Mahmoud Ahmadinejad held talks with Chinese President Hu Jintao in Beijing on Saturday in a rare visit to China coinciding with the start of the Paralympic Games.
Hu said in welcoming words to Ahmadinejad at the Great Hall of the People in Tiananmen Square that the two would discuss Sino-Iranian relations, among other issues, during their meeting.
"I would like to further exchange opinions with you Mr President about issues like Sino-Iranian relations," Hu told the Iranian President.
China is involved in multilateral talks with the United States, Britain, France, Germany and Russia aimed at urging Iran to end its uranium enrichment activities in a long-standing dispute over Tehran's nuclear programmes.
Iran and China are close allies, with Iran's vast oil and gas resources feeding China's growing energy demand. China is also one of the biggest exporters to Iran.
But relations soured when China voted in March for a UN Security Council resolution to tighten sanctions on Iran.
Iran has repeatedly said that it has no intention of halting enrichment despite three sets of UN Security Council sanctions, and US and EU sanctions implemented over fears that Tehran is seeking to produce atomic bombs.
Hu and Ahmadinejad met last week in the Tajik capital of Dushanbe at a summit of the Shanghai Cooperation Organisation (SCO), a regional grouping consisting of Russia, China and four ex-Soviet states.
Iran has observer status at the SCO, which was founded in 2001 as a counterweight to NATO in the strategic Central Asian region.
Ahmadinejad also met with Iranian athletes Saturday afternoon, and is due to attend the opening ceremony of the Paralympic Games, embassy spokesman Mahmoud Rezvani told AFP.
He had originally planned to stay in China's capital for two days, and was to hold a press conference on Sunday, but his stay was cut to one day and the media event cancelled. The embassy did not say why his travel plans had changed.
