Hu said that Europe's debt crisis was "an issue of general concern" and that the other G20 members should "encourage and support efforts made by Europe to resolve it and send a signal of confidence to the market."

"Total global demand remains weak. Growth in major economies is sluggish," he warned, in an interview with the Mexican daily Reforma published on the eve of the G20 summit of the world's leading economies.

Hu was due to join other G20 leaders in the Mexican resort of Los Cabos ahead of the two-day meeting, which is expected to be dominated by the crisis in the eurozone, where states are struggling to pay their debts.

"In the current world economic environment, the G20 members should stick together in difficult times and pursue win-win cooperation," Hu said, according to a translation of the interview by the official Chinese news agency Xinhua.

"In Los Cabos, I look forward to exploring with leaders of other G20 members ways to promote world economic stability, recovery and growth," he added.

Hu was expected to hold several bilateral meetings with senior world leaders, including with US President Barack Obama, on the sidelines of the summit, which begins on Monday and lasts two days.

The conservative New Democracy party won a narrow victory in knife-edge parliamentary polls held Sunday. Its leader, Antonis Samaras, has urged parties that want to stick with the euro to join a coalition.

"We respect the choice of the Greek people. We hope the election result can help stabilise the economy in the eurozone," Chinese foreign ministry spokesman Hong Lei told reporters.

"China is always supportive of the EU and the eurozone's efforts to solve the sovereign debt crisis."

Sunday's elections were followed closely around the world, as a victory for Samaras's main rival Alexis Tsipras -- head of the leftist anti-austerity party Syriza -- may have prompted Greece to exit the eurozone.

New Democracy -- which won just over 30 percent of votes -- will likely form a coalition government with the socialist Pasok party. The two parties have dominated Greek politics for decades and are blamed by many for current woes.

China's official Xinhua news agency on Monday called for a new government to be formed "quickly", adding it would have to convince Greek people "of the need for painful austerity."

"They (political parties) must understand a Greek exit from the eurozone is out of the question," it said, adding that ditching the euro would open a "Pandora's box", leading to "years of painful economic and social adjustments".

Samaras says he wants to ease the terms of an unpopular EU-IMF bailout deal which has imposed harsh austerity measures in return for a multi-billion-euro rescue package.

Greece has been forced to seek bailouts twice, first for 110 billion euros in 2010 and then for 130 billion euros this year plus a 107-billion-euro private debt write-off.

But for many Greeks, a fine-tuning of the terms of the bailout may not be enough as anger is rising against the steep pay and pension cuts seen since the crisis first exploded in 2009, setting off a chain reaction across Europe.

Xinhua called on investors around the world to be patient with Europe.

They "should... give European countries more time to come up with a comprehensive plan to tackle the crisis," it said.

On Sunday Chinese Vice Finance Minister Zhu Guangyao said the IMF would get the $430 billion bailout fund it tentatively announced in April, saying China will "pitch in".
