Finance ministers and central bank governors from 20 industrialized and emerging economies were to start a two-day meeting Saturday in China where they are expected to discuss the impact of soaring oil prices on the global economy, development issues and possibly China's currency reforms.

The G-20 meeting, to be held at Grand Epoch City, a resort near Beijing, is also expected to focus on reforms of the International Monetary Fund and the World Bank, as well as the issues of aging populations and migration, Japanese Finance Ministry officials said.

The G-20 nations have 63 percent of the world's population and account for 80 percent of global output.
