BEIJING - Record number of developing countries will attend the G20 summit in the eastern Chinese city of Hangzhou in early September, said Chinese Foreign Minister Wang Yi on Wednesday.

Wang made the remarks at a press conference together with his Lao counterpart Saleumxay Kommasith after their talks in Beijing.

As the biggest developing country in the world, China has the responsibility of maintaining and expanding the rights and interests of other developing countries, said Wang.

China has invited five developing countries to the G20 Hangzhou summit: Chad, chair of the African Union; Laos, chair of the Association of Southeast Asian Nations (ASEAN); Senegal, chair of the New Partnership for Africa's Development (NEPAD); Egypt; and Kazakhstan.

Thailand, as the chair of the G77 this year, also expressed willingness to attend the Hangzhou summit, said Wang.

"The developing world is best represented in the upcoming summit in Hangzhou, making it the most inclusive," Wang said, adding that China is confident in hosting a successful G20 summit.

The foreign minister said there will be nearly 30 deliverable outcomes at the Hangzhou summit, making it one of the most fruitful summits in G20 history.?
