An American fast-food chain has partnered with a Chinese state broadcaster for its latest advertisement to mark the 40th anniversary of China’s economic reforms.

KFC released the ad Thursday featuring celebrities from two generations — actor Huang Bo and pop idol Lu Han — who time travel on a train, tracing China’s development since it opened to foreign investment in 1978. The two-minute video co-produced with China Central Television highlights the country’s infrastructure advancements, including high-speed railways and the Hong Kong-Zhuhai-Macau Bridge, as well as the technological progress achieved in the last four decades.

KFC was the first fast-food chain to open in China in 1987 and has now over 5,000 restaurants in 1,100 cities. (Image: KFC's official Weibo account)
