Japan is informally considering the establishment of a high-level comprehensive forum for discussing economic issues with China as early as next year to promote policy cooperation in a wide range of areas, government sources said Thursday.

The forum, if actually set up, would cover not only trade and investment but also macroeconomics, finance, industrial cooperation and other areas, the sources said.

China already plays an increasingly important role on the global trade stage, a role that will grow in stature by the end of this year or early next year when the country formally enters the World Trade Organization.
