BEIJING--China had planned to announce a $10 billion infrastructure investment fund and offer credit to neighbors at a cancelled weekend summit of Asian leaders in Thailand, its foreign minister said.

Anti-government protestors forced the cancellation of the summit in Pattaya after they swarmed into the summit venue.

In an interview with state media on a flight back to China, Foreign minister Yang Jiechi avoided direct criticism of the Thai government while detailing measures that Chinese premier Wen Jiabao had planned to offer at the summit.

China plans to establish a $10 billion China-ASEAN investment cooperation fund to promote infrastructure that connects it to ASEAN nations, Yang said.

China has been active in building roads from its southern border through neighboring Myanmar, Laos, and Vietnam, to ease trade.

It will also offer a credit of $15 billion to ASEAN countries, including preferential loans of $1.7 billion for cooperation projects, Yang said.

It plans to offer 270 million yuan ($39.51 million) in aid to Cambodia, Laos and Myanmar to help those impoverished countries combat the global financial crisis, and will inject $50 million into the China-ASEAN cooperation fund, Yang said.

While not an ASEAN member, China's growing economic clout, huge market and competitive exports make it an important participant in ASEAN summits, although tensions persist over competing claims to the South China Sea and Chinese plans for dams that are opposed by other nations along the Mekong river.

China recently appointed its first ambassador to ASEAN, after the 10-member grouping formally adopted a charter.
