What made the business news in Asia and Europe this morning? Here's our daily business round-up:
Key talks between Athens and its private creditors are set to resume to try to agree a debt write-off that would dramatically reduce Greece's debt levels.
The two parties have so far failed to agree an interest rate on new bonds that would replace existing debts.
If agreement can be reached, Greece should be in line for additional bailout funds.
Athens has said it hopes to reach a deal by the end of this week.
As the World Economic Forum (WEF) in Davos continues, David Cameron has told EU leaders they must be "bolder" if they want to shake off their economic troubles.
The UK prime minister told the World Economic Forum in Davos it was a "perilous time" for Europe's economies and "tinkering won't cut it anymore".
He called for a target for reducing Brussels red tape and for the EU to explore new free trade deals.
He also defended his government's austerity plan saying it had helped the UK "get ahead of the markets".
Also at Davos, the Bill and Melinda Gates Foundation has announced it has committed a further $750m (£479m) to a global fund to combat AIDS, tuberculosis and malaria.
"These are tough economic times, but that is no excuse for cutting aid to the world's poorest," said Microsoft founder Bill Gates told the WEF.
The Global Fund is a 10-year-old public-private partnership.
