Greece's government won a vote of confidence late on Tuesday, a crucial step toward securing further financial aid from the European Union as the country tries to avoid the euro zone's first sovereign debt default.
"For the next three years, we're going to see different economies work out different problems. For European economies, especially Greece, it would be through default," Mohamed El-Erian, chief executive of PIMCO, told reporters in Taipei on Wednesday via a video conference.
El-Erian has suggested in the past that Greece would default and that Europe risks wasting money for nothing by pumping billions of dollars into the ailing economy.
He added on Wednesday it was "unlikely but not impossible" that a Greek default would trigger another global financial crisis.
