More than 30 historical photos featuring the collaboration between China and the United States during World War II (WWII) were exhibited at the Los Angeles city hall Tuesday.

"The stories captured in these photographs remind us of the common humanity that unites our two nations," Los Angeles Mayor Eric Garcetti, who was not able to attend the opening ceremony of the exhibition Tuesday, said in a message delivered by Deputy Mayor Jeff Gorell.

The exhibition was co-organized by the Chinese Consulate-General in Los Angeles and the Office of Mayor Garcetti, and supported by the China Overseas Exchange Association. This year marks the 70th anniversary of the end of World War II.

"The exhibition is a chance to recall the common cause that bound together two great Pacific nations: the US and China. Serving side by side, the two nations forged legendary friendships that transcended race, language and culture...The exhibition celebrates those collective memories that today continue to inspire collaboration and peace," the mayor's office said in a statement.

The photos displayed were taken by the US 164th Signal Photo Company during the war, highlighting renowned historical figures such as General Joseph Stilwell, General Claire Lee Chennault of the American Flying Tigers, and top Chinese leaders. They also showcased images of soldiers, medics and civilians, the many unsung heroes from both countries who were united in a valiant cause.

"The precious old photos bring us vivid memories of the war and render us a direct knowledge and perception of history and significance of the China-US cooperation," said Chinese Consulate General Liu Jian at the ceremony attended by dozens of Los Angeles and Chinese officials and representatives from different organizations.

"In memory of the young men and women who sacrificed their lives for peace and justice, the photos call upon us not only to stand vigil for peace and defend the achievements of WWII, but also to pass on the legacy to the future by building upon what we have achieved in the China-US cooperation with a positive attitude and tangible actions," Liu said.

"When you see people were working together, remember that we were together to fight," Gail Soffer, who visited the exhibition, told Xinhua.

"In the future, the world nations need to do more cooperations, especially these days in the fighting against greenhouse gases, global warming and other environmental problems. It will be a good idea for us to get along better," she added.
