He Yafei says China is willing to "engage" on emissions monitoring

China signalled concessions⁵ on monitoring of emission³ curbs⁶, and the US said it would commit money for developing countries.

Leaders are likely to have big choices to make when they meet on Friday.

However, a leaked document from the UN climate convention大会，协定 indicates the best deal likely here will not keep the temperature rise below 2C (3.6F).

Even if countries implement实施，执行 their biggest pledges, a rise of 3C (5.4F) is indicated, it concluded.

Money matters

Despite many expressions of concern about projections预测，投影 of climate change, finance has emerged as an issue more likely to make or break a deal than emission pledges.

US Secretary of State Hillary Clinton said her administration was prepared to help establish funding of $100bn a year for developing countries if a deal emerges here that meets US requirements.

"In the context of a strong accord符合，一致 in which all major economies pledge meaningful mitigation减轻，缓和 actions and provide full transparency as to those actions, the US is prepared to work with other countries towards a goal of mobilising $100bn a year to address the needs of developing countries."

The key demand is "transparency" from China, seen as a must if the US Senate is to pass legislation controlling emissions.

But the Beijing government has been hostile to对……有敌意的 this notion概念，见解; and the issue had emerged as, in Mrs Clinton's words, a "deal-breaker".

But here, Vice⁹ Foreign Minister He Yafei has said China was ready to engage in "dialogue and co-operation that is not intrusive侵入的，打扰的, that does not infringe¹¹ on侵害，破坏 China's sovereignty主权."

Earlier, Indonesia's President Susilo Bambang Yudhoyono had called for "all of us, developed and developing countries, to be flexible" on verification确认，核实.

He indicated the possibility of setting up an international mechanism¹² for monitoring emission cuts.
