World leaders have asked Australia to host the G20 leaders summit in 2014, as plans to get Europe back on track failed but progress was made on global trade and jobs.

Prime Minister Julia Gillard, who will get to set the summit agenda, said she would consult with the state premiers on who would host the event.

"Hosting the G20 will allow Australia to set and shape the international agenda on issues of fundamental importance to our national interest, including the health of the global economy, financial regulation, trade, jobs and clean energy," she said.

While the final communique spelled out plans for a jobs task force, stronger powers for the bank watchdog, financial sector reform and a way forward for the stalled Doha trade round, the leaders failed to agree on the future direction for Europe.

With European finance ministers due to meet next week, the only successes being claimed were convincing Greece to back down from a referendum on its bailout and Italy agreeing to get its budget back into surplus in 2012 and provide regular reports on its efforts to stave off a crisis.

G20 finance ministers, including Treasurer Wayne Swan, are set to meet as early as December to flesh out the details of how much the International Monetary Fund's resources will be bolstered.

Australia and China are among a number of countries to pledge extra resources for the IMF, while steering clear of the European Financial Stability Facility set up to stop the spread of the debt crisis.

The IMF is likely to put in place a new short-term credit line to help countries facing economic shocks that they can't immediately handle.

The extent of the global problem was shown in figures released by the Reserve Bank, which forecast GDP growth of 3.25 per cent for 2011/12, rather than the four per cent it had predicted in August, while for 2012/13 it forecasts GDP of 3.25 per cent rather than 3.75 per cent.

The Greek situation dominated much of the talks, with Greek politicians preparing to vote on a motion of confidence in the government of Prime Minister George Papandreou around midnight Athens time (0900 AEDT Saturday).

The governing Socialists have a slim two-seat majority in the 300-member legislature, and at least one MP has publicly threatened to vote against the government.

Ms Gillard said the best way forward for Greece is to swing behind the efforts of G20 leaders who want the nation to succeed, and not see its debt problems infect the rest of the global economy.

The leaders backed a plan being driven by Australia to set a road map for trade as the Doha round comes to a halt.

The round will be broken into more achievable pieces, with the first of these - in terms of Australia's focus - being reforming trade facilitation, such as fishing subsidies, and helping low-income countries.

Ms Gillard said the action plan on jobs and growth is the first time that G20 nations have committed to a united effort to tackle the issue.

Every country's actions will be monitored and a report provided to the summit in Mexico in 2012.

Before she left France, the prime minister briefly met with Microsoft founder and philanthropist Bill Gates, who addressed the G20 on a plan to find better ways to raise money to feed the world's poorest people.

Russia will host the G20 in 2013 and Turkey in 2015.

The issue of climate change was discussed, with the leaders calling for the Cancun agreements to be implemented, including the Green Climate Fund, and handing the G20 finance ministers the job of finding innovative ways to fund climate action.

Welcome from the French G20 presidency

France is very honored to chair the Group of Twenty in 2011.

The G20 was established in 1999, in the wake of the 1997 Asian Financial Crisis, to bring together major advanced and emerging economies to stabilize the global financial market. Since its inception, the G20 has held annual Finance Ministers and Central Bank Governors' Meetings and discussed measures to promote the financial stability of the world and to achieve a sustainable economic growth and development.

To tackle the financial and economic crisis that spread across the globe in 2008, the G20 members were called upon to further strengthen international cooperation. Accordingly, the G20 Summits have been held in Washington in 2008, in London and Pittsburgh in 2009, and in Toronto and Seoul in 2010.

The concerted and decisive actions of the G20, with its balanced membership of developed and developing countries helped the world deal effectively with the financial and economic crisis, and the G20 has already delivered a number of significant and concrete outcomes:

First, the scope of financial regulation has been largely broadened and prudential regulation and supervision have been strengthened. There was also great progress in policy coordination thanks to the creation of the framework for a strong, sustainable and balanced growth designed to enhance macroeconomic cooperation among the G20 members and therefore to mitigate the impact of the crisis. Finally, global governance has dramatically improved to better take into consideration the role and the needs of emerging of developing countries, especially through the ambitious reforms of the governance of the IMF and the World Bank.

Building on these important progresses, the G20 has now to adapt to a new economic environment. It must prove that it is able to coordinate the economic policies of major economies on an ongoing basis.

2011 will be the occasion to build on the recent successes of the G20 and ensure an active follow-up on processes already underway. It will also be the time to address other essential issues which are crucial to global stability such as the reform of the international monetary system and the volatility of commodity prices.

We believe indeed that today's key economic challenges require a collective and ambitious action which the G20 is able to impulse.
