Russian Prime Minister Dmitry Medvedev extended his congratulations to Hun Sen for being re- elected as the Prime Minister of Cambodia for another five-year term after his ruling party won the July 28 election.

"I congratulate you on taking up the post of Prime Minister of Cambodia for another term," he said a message, which was released to the media by Cambodian Ministry of Foreign Affairs on Wednesday.

"I am convinced that the development of traditionally friendly Russian-Cambodian relations, strengthening of cooperation in trade, economic, cultural and other fields fully meets the interests of the peoples of our countries," he said.

Cambodian parliament, formed by the ruling party's 68 lawmakers, on Tuesday voted for the formation of a new government under the leadership of Hun Sen, even though the opposition's 55 legislators boycotted the session since the party refused to accept the results of the July 28 election.

Hun Sen said Tuesday the new parliament and government were formed in accordance with the constitution despite a boycott of the opposition.

He said, under the constitution, a new government was formed by a 50 percent plus one majority, or 63 lawmakers, in the parliament.

Hun Sen, 61, who has been in power for 28 years, was sworn in for another five-year term on Tuesday.
