A photo exhibition on China's relief efforts after the May 12 devastating earthquake was launched in this Portuguese capital Monday.

The month-long exhibition, hosted by the Chinese Embassy, displayed nearly 100 photos taken by Xinhua journalists in Sichuan after the earthquake hit the southwestern province.

The exhibition shows the destruction wrought by the quake, China's relief in the disaster-hit regions and the international aid efforts, Ana Rodriguez, a visitor, told Xinhua.

Opening the exhibition, Jin Hongjun, charge-de-affairs of the Chinese embassy, voiced his appreciation of the aid and moral support offered by the Portuguese government and people to China in its relief efforts.

A devastating earthquake measuring 8.0 on the Richter scale hit China's southeastern region on May 12, leaving about 70,000 people dead, 374,000 injured and 18,000 missing.
