Mayor London Breed of San Francisco in the west U.S. state of California Friday declared upcoming China's National Day as Chinese-American Friendship and Heritage Day in San Francisco to underpin the city's desire to expand cooperation with China. 美国加州旧金山市长伦登·布里德周五宣布，将即将到来的中国国庆节作为旧金山的中美友谊和传统日，以巩固该市与中国扩大合作的决心。 The San Francisco City Council held a ceremony at the City Hall Friday morning to celebrate China's National Day, which falls on Oct. 1. Breed issued the Proclamation on Chinese-American Friendship and Heritage Day to congratulate the Chinese people on the national celebration, the first time she extended her personal greetings to the Chinese people on the occasion of China's National Day since she took office in July this year. San Francisco has a longstanding history of openness and respect for people of all backgrounds, and it recognizes the important contributions made to the city by Chinese and Chinese-Americans, she said. "This year marks the 39th anniversary of the founding of the San Francisco-Shanghai Sister City relationship, and we recognize the volunteers of our Sister City Committee who promote mutual respect, understanding, and cooperation between the people of both cities," Breed said. She noted that the celebration of China's National Day offers an opportunity to reaffirm San Francisco's commitment to encouraging deeper connections between the Chinese people and San Francisco.
