阮富仲
According to Tuong Vu, an associate professor at the University of Oregon, there exists a rivalry between Trương Tấn Sang, Nguyễn Phú Trọng, Nguyễn Sinh Hùng, the Chairman of the National Assembly, and others against Nguyễn Tấn Dũng and his supporters. According to several diplomats and Western academics, Trương Tấn Sang, during the run-up to the 11th National Congress, tried to supplant Nguyễn Tấn Dũng as prime minister. In this he failed, and he was instead appointed to the largely ceremonial post of President. One of the most outstanding critiques of Nguyễn Tấn Dũng's economic policy is his handling of the state-owned sector; state companies have preserved Soviet-like working ethics, together with large loans, and overextended growth led to a meltdown of two high-profile state-owned companies; both Vinashin and Vinalines both required government rescue. Nguyễn Tấn Dũng's has also been criticised by his handling of corruption; several corruption scandals became public during his first term as prime minister. Following the 6th plenum of the Central Committee, Nguyễn Phú Trọng said a vote of confidence would be introduced in 2013.
