President Hu Jintao arrived in New Delhi Monday for a four-day visit that it is hoped will see China and India establish a more trusting relationship, Reuters reported. Hu's trip to India is only the second by a Chinese president. It follows Jiang Zemin's 1996 visit during which the sides agreed to reduce tensions along their disputed Himalayan border, which sparked a brief war in 1962. The two nations are forging lucrative bilateral trade ties but suspicions remain. China is concerned about India's growing relationship with the US, its support for Tibetan refugees and fast developing naval strength in the Indian Ocean. Meanwhile, India can point to China's traditional support of Pakistan and Beijing's alleged unwillingness to compromise over the border dispute. Agreements are expected to be signed on defense cooperation, bilateral investment protection, the promotion of regional trade and the establishment of closer diplomatic, cultural and transport links.
