A week after hosting China's new Premier Li Keqiang, Indian Prime Minister Manmohan Singh is visiting Japan this week in a bid to deepen strategic and economic ties with Shinzo Abe's administration. Singh's sojourn is being watched with interest by China, whose relations with both nations are troubled. The trip also offers an interesting study in trilateral dynamics between Tokyo, Delhi and Beijing, apart from providing a snapshot of how the Indian engagement with Japan might have an impact on China's attitude towards Delhi.
