On the very day Xi arrived in the Cambodian capital of Phnom Penh in 2016 for a state visit, he made a special visit to the royal palace to see Queen Mother Norodom Monineath Sihanouk. The queen mother invited Xi to sit in a chair that was frequently used by her late husband, King Father Norodom Sihanouk.

This chair had been meticulously preserved by the Cambodian royal family since the king father's passing -- covered and untouched, until Xi's visit.

"This is a privilege reserved only for the most esteemed and dearest friends," explained Princess Norodom Arunrasmy, who was present.

With a warm smile, Xi spoke fondly of King Father Sihanouk, describing him as "a revered friend of the Chinese people and a symbol of China-Cambodia friendship." The king father's deep personal ties with Chinese leaders since the 1950s have played a pivotal role in fostering the ever-refreshing friendship between the two countries.

More than once, Xi has quoted an old Chinese saying to underscore how the China-Cambodia friendship has withstood challenges and global transformations: "A long journey tests a horse's strength, and a long span of time reveals a person's heart."

In Xi's signed article published by Cambodian media prior to his 2016 visit to the country, he noted that China will never forget Cambodia's role as one of the first nations to recognize the People's Republic of China and a champion of China's rightful seat at the United Nations.

The friendship between the two close neighbors has always been mutual. China has been a steadfast partner of Cambodia, supporting its national independence and economic development, including the construction of Cambodia's first cement plant and thermal power station.
