Greek Prime Minister Alexis Tsipras arrived in Brussels for an emergency eurozone summit Monday ruling out pension cuts, higher power rates, and excessive budget surpluses in a deal with the debt-swamped country's creditors.

"We're here to conclude a viable economic accord," Tsipras said ahead of talks with Greece's creditors, the European Union, European Central Bank and International Monetary Fund. A statement issued by Tsipras's office said the "keys to such an accord" included "abandoning excessive primary (budget) surpluses, protecting salaries and pensions, avoiding excessive and unreasonable hikes in electricity (prices)."
