Finance officials from the Group of 20 richest nations are set to outline a commitment to boosting the global economy when they meet in London later.

20富国集团的财务官员在即将举行的伦敦峰会上将要制定出振兴全球经济的大体方案。

Some do not expect any major announcement from the talks

They are gathering¹ as friction²（摩擦） mounts over when to scale down stimulus³ efforts as signs of recovery emerge.

However, while there is expected to be consensus⁴（一致，合意） over continuing to spend, a proposal to curb⁵ bankers' bonuses may face US and UK opposition⁶.

A full G20 meeting takes place in Pittsburgh later this month.

US Treasury⁷ Secretary Timothy Geithner said he did not expect any major announcements to emerge from the London talks.

With Japan, France and Germany officially out of recession, minds are turning to co-ordinating the withdrawal⁸ of billions of aid and stimulus measures that were injected into countries by their governments over the past year.

And finance ministers and central bankers are set to co-ordinate plans for the eventual⁹ tapering¹⁰ off of government support.

Other financial reforms are up for discussion, including the a US proposal for a international agreement on forcing banks to increase their capital reserves to help prevent another financial crisis.

The leaders of the UK, France and Germany have said the G20 group must adopt "binding¹¹ rules" to regulate bank behaviour.

UK Prime Minister Gordon Brown, French President Nicolas Sarkozy and German Chancellor¹² Angela Merkel made the comments in a joint¹³ letter.

They also agreed to explore ways of limiting bonuses at banks to prevent future financial meltdowns, saying banks could not go on as if the crisis never happened.

UK Chancellor Alistair Darling told the CBI in Scotland, that bonuses were not a problem if they were "deserved for long term success or hard work" but added "a bonus shouldn't be guaranteed, it should be earned".

He echoed the view that nations must work together, saying international co-operation was needed to "prevent banks playing one country off against another".

'Reprehensible¹⁴'

In the letter, the three leaders say "speculative¹⁵ activities that constitute（构成，组成） a risk to financial stability should also be discouraged by increasing capital requirements".

They also discussed bankers' pay, which has been the subject of much debate in the run-up to the G20.

"We should explore ways to limit total variable（可变的，易变的） remuneration（报酬） in a bank either to a certain proportion of total compensation or the bank's revenues and/or profits," they said.

"Our citizens are deeply shocked at the revival¹⁶ of reprehensible（应该谴责的） practices, despite taxpayers¹⁷' money having been mobilised to support the financial sector¹⁸ at the height of the crisis," the letter said.

"The abatement¹⁹（减轻，缓和） of financial tensions has led some financial institutions to imagine they can return to the same modes of action prevalent（流行的，普遍的） before the crisis. This is not an option."

The statement is a sign of unity²⁰ on bank bonuses, after mixed signals on the European Union's willingness to act on the issue.

France is proposing a series of mandatory²¹（命令的，强制性的） caps on bonuses - which the head of the Eurogroup of eurozone finance ministers, Luxembourg's Jean-Claude Juncker, said he "totally supported".
