As China Looms, Vietnam Aims to Develop a More Modern, Skilled Navy Ralph Jennings TAIPEI - A Vietnamese military official advocates developing a more modern, better skilled navy that can hold off complex threats, mainly what experts believe to be increasing pressure from China. A rear admiral and political commissar in Hanoi told the official Viet Nam News August 6 that the navy could not be "taken by surprise at any development. "In this complicated situation that poses many threats to the country's defense and security, given the Navy's role as the key defender of the country's sovereignty, the Viet Nam People's Navy must do more to build a strong, developed, skilled and modern naval force that can fulfill all assigned missions," said the commissar, Phạm VÄn Vững. The commissar's words follow the sinking of a Vietnamese fishing vessel in March-- Vietnam says at the hands of China. More recently, Chinese coast guard boats have approached a Vietnamese undersea energy exploration site near Vanguard Bank in the South China Sea. China and Vietnam vie for sovereignty over tracts of the sea where these two incidents have occurred. These two upsets are just the latest between the territorial rivals dating back centuries. .
