The King of Tonga, George Tupou V, says he supports the measures adopted by China to handle the disorder in Tibet.
The king made the comment in China where he is on a state visit as guest of President Hu Jintao.
The Xinhua news agency quotes the king as saying that China's affairs can only be tackled by China and no interference from any foreign country is acceptable.
The king also re-stated Tonga's support of the one-China policy.
President Hu said this year marked the 10th anniversary of the establishment of diplomatic ties between China and Tonga which previously had recognised Taiwan.
