After the military coup, they overthrew Sihanouk's regime and later sentenced Sihanouk to death. But because Sihanouk was on a state visit at the time of the coup, he was on a state visit to Moscow at that time, and then the Soviet people told him that there was a coup in Cambodia. Later, Sihanouk was forced to fly to China. It is said that Sihanouk cried on the plane because the regime was overthrown and Cambodia was in chaos. Of course, the life of the Cambodian people is certainly difficult, because after all, that regime is a pro-American traitor.
At that time, Sihanouk lived in Beijing temporarily, and during his stay in China, he also established a government in exile, called the National Coalition Government of the Kingdom of Cambodia. The slogan of this government is to overthrow the Lang Nuo regime, to overthrow this pro-American and treason regime. But after all, because of the disparity in strength, the regime was suppressed.
But in the end, with the support of other forces, the Lang Nuo regime was defeated. Later, Sihanouk returned to China, but after returning to China, he was placed under house arrest and had no real power. Roughly speaking, Sihanouk has been in exile in China for nearly 48 years. Sihanouk had a rough life. The regime change forced him into exile for so many years. Fortunately, he returned to his country in his later years. Although there was no real power later, it still had a reputation.
