"When the Vietnamese came to the rescue and invaded Cambodia in 1979, Pot retreated to the jungle, though he continued to orchestrate guerilla attacks until his arrest in 1997."

Vietnam invaded and occupied Cambodia for 10yrs.
They did not rescue or save any Cambodians.
All they did was start a new war and prolong the suffering of the Cambodian people.The Viets are actually responsible for half of the land mines laid in Cambodia.Vietnam is the backer of present day evil,murderous Hun Sen regime in Cambodia
