"Climate Talks Struggle As China, U.S. Face Off"

"The United States and EU said on Wednesday that U.N. climate talks were making less progress than hoped due to rifts over rising economies' emission goals, while China pushed back and put the onus on rich nations.

Negotiators from 177 governments are meeting this week in the northern Chinese city of Tianjin, trying to agree on the shape of the successor to the current phase of the Kyoto Protocol, the key U.N. treaty on fighting global warming, which expires in 2012.

Midway through the talks, however, initial hopes that they can deliver progress on trust-building goals have become snared in procedural skirmishing that boils down to feuding over how far rich and emerging nations should curb their greenhouse gas emissions and how they should check on each other's efforts.

Negotiators said the contention could damage prospects for negotiations late this year in Cancun, Mexico, which are intended to lay the foundations for a new, legally-binding climate pact."
