One of them is a proposal to eliminate tariffs on environmental and clean-energy technologies. In his talks with Hu, Bush invited the Chinese leader to consider doing the same, said Dan Price, a presidential economic adviser on the National Security Council.
''President Bush raised the issue of climate change, and both sides welcomed the attention of APEC to climate, and they confirmed the importance of addressing this pressing problem cooperatively and responsibly, and in a manner that did not stall or stunt economic growth,'' Price said.
Hu had suggested the United Nations should be the one to spearhead climate control efforts. Price said that wasn't necessarily contradictory with the Bush approach.
The U.S. and Chinese leaders also talked about North Korea, Iran and Chinese product safety. Hu ''was quite articulate about product safety, and I appreciated his comments,'' Bush said. White House aides later said Hu expressed a willingness to step up Chinese efforts to ensure the safety of products and to crack down on efforts to ship tainted foods.
Bush said he accepted Hu's invitation to attend the 2008 Summer Olympics. And the two leaders talked about establishing a ''hot line'' like the longtime one between Washington and Moscow to alert each other to possible military situations that might seem threatening or be ambiguous.
Both leaders expressed opposition to efforts within Taiwan to seek U.N. membership. The U.S. has opposed steps toward independence for the self-governing island, which Beijing considers a renegade province, preferring to adhere to its ''One China'' policy even as it continues to sell military supplies to Taiwan.
Bush has called for greater reliance on technology to combat global warming. Although early in his first term, he had insisted that the science of what causes global warming was not yet settled, more recently he has been less questioning of a link between human activity and higher global temperatures, and supportive of programs to tackle the problem.
Earlier this week, Bush said it was an ''urban legend that is preposterous'' for critics to suggest that his opposition to the Kyoto treaty showed a lack of environmental awareness or concern about climate change.
Bush was also having lunch with South East Asian leaders and meeting with South Korean President Roh Moo-hyun and Putin.
In his speech, the president was also issuing an appeal to Asia-Pacific business leaders for their help in getting stalled global trade liberalization talks restarted.
The trade talks known as the Doha round have stumbled since their inception in Qatar's capital in 2001, largely because of wrangling between rich and poor countries over eliminating barriers to farm trade and, more recently, manufacturing trade.
