TOKYO (Reuters) - The United States is considering inviting Singapore and Thailand to a Group of 20 summit in Pittsburgh this month to reflect broader views from developing countries, Japan's Nikkei business daily reported without citing sources.

With participation of the two Asian nations, Washington is also hoping to balance the growing influence of European countries in talks on issues such as financial regulation and global warming, the Nikkei said.

On pay and bonuses in the financial sector, France and Germany have pushed hard for limits, while Britain, the United States and Canada have opposed caps.

Washington is considering having Singapore represent the Asia-Pacific Economic Cooperation (APEC) forum and Thailand as a representative of the Southeast Asian grouping ASEAN, the Nikkei said.

Their participation is expected to enable the G20 to hold substantive talks on issues including support for developing countries in cuts on CO2 emissions, and strengthening their voice at the International Monetary Fund, it said.
