TEHRAN, April 26 (Xinhua) -- The first batch of emergency aid materials from the Chinese government to Iran's flood-hit areas landed in the capital Tehran on Friday.

Chinese Ambassador to Iran Pang Sen handed over the aid materials to an Iranian representative after a brief signing ceremony.

Among the materials are 2,600 waterproof camps, which were carried by a cargo plane belonging to the China Cargo Airlines.

"On the basis of our mutual friendship, we are willing to help the Iranian people within our reach," Pang said.

Iran's Foreign Ministry expressed its gratitude to China.

More Chinese aid, including lifeboats, life vests and diesel generators, will arrive in the coming days.

Continuous rainy days started to hit Iran in late March, where floods invaded at least 25 out of the country's 31 provinces, causing economic losses worth hundreds of millions of U.S. dollars and dozens of casualties.
