New Delhi's decision to reopen air force bases near the Chinese border has also invited negative reactions from officials in Beijing, ANI reported quoting experts.
Encouraging India's role as a counter to China, the U.S. too has stepped up exercises with the Indian navy and last year sold it an American warship for the first time, the 17,000-ton amphibious transport dock Trenton.
American defense contractors have also been offering India's military everything from advanced fighter jets to anti-ship missiles.
"It is in our interest to develop this relationship," U.S. Defense Secretary Robert Gates said during a visit to New Delhi in February.
"Just as it is in the Indians' interest."
Officially, China says it's not worried about India's military build up or its closer ties with the U.S.
However, foreign analysts believe China is deeply concerned by the possibility of a U.S.-Indian military alliance.
