Vietnamese Prime Minister Nguyen Tan Dung and former Thai Prime Minister Thaksin Shinawatra visited Cambodia on Sunday to pay their last respect to Hun Neang, Prime Minister Hun Sen's father, who died of natural causes at the age of 90 on Friday.

The state-owned National Television of Kampuchea reported that Nguyen Tan Dung and Thaksin Shinawatra paid their tribute to late Hun Neang separately on Sunday afternoon at Prime Minister Hun Sen 's residence near the Independence Monument in Phnom Penh.

The two high-profile figures expressed their condolences to Hun Sen over the death of his father, and Hun Sen extended his gratitude to them for traveling to Cambodia for the funeral.

Thaksin, deposed in bloodless coup in 2006, is a close friend of Hun Sen and used to be the economic advisor to the Cambodian government and Hun Sen from November 2009 to August 2010.
