The Chinese government media suggested that Japanese Prime Minister Yoshihiko Noda’s ongoing visit to India was part of a “containment strategy” aimed at China.
Chinese Government explained that it wanted to “actively develop” relations with both countries, 
allegation is that Japan, India and some of China’s other neighbours were part of a United States-led effort to contain China’s rise  or Japan’s strategy of strengthening alliances with Asia-Pacific nations with an eye on China
Japan’s “Arc of Freedom and Prosperity” strategy has been interpreted as an effort to contain China
Japan and India have comprehensively boosted regional cooperation in recent years, not only in security but also in economic ties, the cooperation has been moving from bilateral to multilateral, trying to include the United States, Australia and India in its Arc of Freedom and Prosperity.”
U.S. is seen as “intensifying ‘security rebalancing’ efforts on China” , “instigating its allies to pay, contribute and appear to restrain China  and “strengthened penetration in China's surrounding regions through humanitarian aids, military exchanges and arms sales.”
Japan and China in the recent meetings reached a consensus that “peaceful coexistence, mutually beneficial cooperation and common development serve the interests of the two countries and two peoples"and the situation in North Korea following the death of Kim Jong-il was reviewed rather than the recent strains in ties over maritime disputes.
The two countries also signed a landmark deal to enable both countries to trade in each other’s currencies and reduce their reliance on the dollar, with Japan expected to purchase US$ 500 million worth of Chinese government bonds
