The sitting Buddha was uncovered by heavy rain at Ta Prohm temple in the Angkor Wat complex in Siem Reap, said Im Sokrithy, deputy director of the local department that oversees the area.
Another statue was found beside a path and that led to the discovery of the bigger statue under a tree.
The temple is undergoing a $4 million restoration by an Indian-led team.
"It is indeed a magnificent example of Khmer art," said Saurav Ray, first secretary at the Indian Embassy in Phnom Penh.
"Both statues are wonderful pieces of Angkorean art and are among the most valuable findings in recent history, beyond doubt," he said.
