Brown said he would work to set global principles and standards for salaries in the financial sector during next week's G-20 summit in London.

Brown promised "detailed results" from the summit. He also said the current crisis was a result of growing globalization.

Brown also expressed optimism the global crisis would eventually result in a stronger world financial system. But he warned against a tendency toward increased protectionism.
