The decision to go ahead with the mission is certain to anger China, which said last month it would "never allow any country" to violate its territorial waters and airspace around the islands, the Washington Post reported.
China on Wednesday said the US' naval and air incursions in the artificial islands in the South China Sea will be counter-productive leading to "miscalculation" and "crisis", as Beijing summoned the American ambassador to protest the US Navy's sailing of a warship into the disputed waters.
Amid tensions over the South China Sea, China on Wednesday warned the United States not to take "dangerous actions" that threatens its sovereignty and security interest, days after an American destroyer patrolled the disputed area.
In a setback for China, an international arbitration court ruled that it has jurisdiction to hear some territorial claims the Philippines has filed against it over disputed areas in the South China Sea, a ruling rejected by China as null and void.
The war of words between China and the US heated up on Tuesday with an American Admiral defending last week's US naval ship's foray near Chinese-made artificial islands in the area while Beijing blasted the move as a "blatant provocation".
Since 55 per cent of Indian trade passes through the South China Sea, and with over $5 billion investments in the energy sector in Vietnam, it is imperative India actively pursues its national interests in the region, says Srikanth Kondapalli.
