Vietnam has discreetly fortified several of its islands in the disputed South China Sea with new mobile rocket launchers capable of striking China’s runways and military installations across the vital trade route, according to Western officials.
Diplomats and military officers said that intelligence shows Hanoi has shipped the launchers from the Vietnamese mainland into position on five bases in the Spratly islands in recent months, a move likely to raise tensions with Beijing.
The launchers have been hidden from aerial surveillance and they have yet to be armed, but could be made operational with rocket artillery rounds within two or three days, according to the three sources.
Deputy defence minister, senior Lieutenant-General Nguyen Chi Vinh, told in Singapore in June that Hanoi had no such launchers or weapons ready in the Spratlys but reserved the right to take any such measures.
“It is within our legitimate right to self-defense to move any of our weapons to any area at any time within our sovereign territory,” he said.
The move is designed to counter China’s build-up+ on its seven reclaimed islands in the Spratlys archipelago. Vietnam’s military strategists fear the building runways, radars and other military installations on those holdings have left Vietnam’s southern and island defenses increasingly vulnerable.
Military analysts say it is the most significant defensive move Vietnam has made on its holdings in the South China Sea in decades.
Hanoi wanted to have the launchers in place as it expected tensions to rise in the wake of the landmark international court ruling against China in an arbitration case brought by the Philippines, foreign envoys said.
The ruling last month, stridently rejected by Beijing, found no legal basis to China’s sweeping historic claims to much of the South China Sea.
Vietnam, China and Taiwan claim all of the Spratlys while the Philippines, Malaysia and Brunei claim some of the area.
“China’s military maintains close surveillance of the situation in the sea and air space around the Spratly islands,” China’s defense ministry said in a faxed statement to Reuters.
“We hope the relevant country can join with China in jointly safeguarding peace and stability in the South China Sea region.”
