Aerial photo taken on Nov. 15, 2020 shows a concrete mixing plant at the construction site of the first expressway in Cambodia in Kampong Speu Province, Cambodia. Despite all the obstacles brought by the COVID-19 pandemic, the construction of the first expressway in Cambodia continues to make headway day by day under a joint effort made by Chinese and Cambodian workers. Connecting the capital city of Phnom Penh and the deep-sea port province of Preah Sihanouk in southwestern Cambodia, this 2-billion-U.S.-dollar Chinese-invested expressway is expected to become the artery of Cambodia's economy.
