US President Barack Obama on Sunday said he planned more talks with China and Russia over Iran's nuclear programme, saying the Iranian government was "isolated" and that China and Russia shared the US objectives, dpa reported.
"We're going to explore every avenue to see if we can solve this problem diplomatically," Obama told reporters after talks with Asia-Pacific Economic Cooperation (APEC) leaders.
UN sanctions were "stronger than ever" after backing by Russia and China, and they appeared to be weakening Iran's economy, he said.
But he said the United States was "not taking any options off the table" in its bid to get Iran to end the "weaponization" of its nuclear programme.
"China and Russia have the same aims, the same objectives, and I believe we'll cooperate closely on that issue," he said. "We will be consulting with them carefully over the next several weeks to look at what other options we have available to us."
Obama held separate talks with Russian President Dmitry Medvedev and Chinese President Hu Jintao on the sidelines of the weekend APEC summit.
"All three of us entirely agreed on the objective," he said, adding that the United States had already succeeded in "isolating the Iranian regime."
"Not only the world but also the Iranian regime understands how determined we are," Obama said.
The International Atomic Energy Agency said in a report last week that Iran since 2008 had refused to answer questions about its alleged research on nuclear weapons. The report described indications from various sources that Iran had carried out such work.
Western nations are seeking to condemn Iran in a resolution when the IAEA governing board meets starting Thursday.
