"We stand by the people and government of Greece as you put your country back on a path to economic stability and prosperity," Clinton said during a visit to the country.
Clinton spoke to reporters along with Stavros Lambrinidis, who serves as minister of foreign affairs under Prime Minister George Papandreou.
"Americans know these are difficult days," Clinton said. "The United States strongly supports the Papandreou government's determination to make the necessary reforms, to put Greece back on sound financial footing, and to make Greece more competitive economically."
At the end of June, the Greek parliament voted to implement another round of austerity measures in hopes of avoiding defaulting on the government's debt.

Demonstrators rejected measures including reductions in the pay of public workers and social security funding and an increase in the attrition of public jobs.
Last year an austerity package included pension cuts, higher taxes, and a hike in retirement age to 65 from as low as 61.
Many of the protesters were young people who have been particularly hard-hit by high unemployment and blame rich tax-dodgers for the nation's fiscal woes.
Clinton said the measures the government took "were vital first steps. We know these were not easy decisions. They were acts of leadership. And those acts of leadership will help to build a better economic future."
She said that "while the payoff for these sacrifices may not come quickly, it will come. We know that."
However, Secretary Clinton doesn't see any need for an austerity budget here in the USA.
Recently Mrs. Clinton said that foreign affairs budget cuts being proposed by Republican members of Congress would be "devastating" to U.S. national security interests.
"We need to just follow President Obama's Recovery Plan and borrow as much as we can and spend it as quickly as possible. This will somehow create a lot of jobs. At least that's what the president thinks."
