Indiaâ€™s annual defence budget is just one-third of that of China despite the tensions that remain along their shared border, according to a Pentagon report. The official annual defence budget of China in the year 2013 was $119.5 billion against Indiaâ€™s $39.2 billion, the Pentagon said on Thursday in its annual report on China, which was submitted to the Congress. For comparison, the national defence budget of Russia in the year 2013 was $69.5 followed by that of Japan â€” $ 56.9 billion. The annual budget of South Korea was $31 billion, the Pentagon said adding that tensions remain along the India- China border. â€œDespite improving political and economic relations between China and India, tensions remain along their shared 4,057-km border, most notably over Arunachal Pradesh, which China asserts is part of Tibet, and over the Aksai Chin region at the western end of the Tibetan Plateau,â€ the Pentagon said.
