Greece's government borrowing rates have dropped to their lowest level in nearly six months as investors welcomed the start of talks between Athens and bailout creditors on how to lighten the country's debt load.

The yield on Greece's 10-year bonds dipped to 7.69 percent, the lowest of the year, while shares on the Athens Stock Exchange were up 2.7 percent in late trading Tuesday amid gains across Europe.

Eurozone finance ministers on Monday formally launched debt relief talks with Greece after the country's parliament approved another major package of austerity measures.

In Brussels, Commission spokeswoman Annika Breidthardt said the European Union's executive branch would offer "technical expertise" to help the debt talks and conclude a long-delayed review of Greece's bailout program.
