“The Chinese side is fully aware of India's position and our concerns about Chinese activities,” foreign ministry spokesman Vishnu Prakash said in response to a Chinese statement that it would remain engaged in Pakistan.

“We hope that the Chinese side will take a long term view of the India-China relations and cease such activities in areas illegally occupied by Pakistan,” Prakash said.

India and China traded diplomatic jabs Tuesday over a recent visit by Indian Prime Minister Manmohan Singh to an Indian border region at the core of a long-standing dispute between the neighbors.

Singh visited Arunachal Pradesh in northeastern India on October 3 to campaign ahead of state elections there, but refrained from saying anything on China or the border dispute.

Last month, China offered financial help to Pakistan to build a multi-billion-dollar dam in Pakistan-administered Kashmir, which led New Delhi to complain to Islamabad.

India and Pakistan have fought two wars over Kashmir, which is administered by the two countries but claimed by both sides in full. The region was split following the partition of the subcontinent at the end of British rule in 1947.

India and China also fought a brief but bitter border war in 1962.

The planned US$12.6 billion Diamir-Bhasha dam on the Indus river in Pakistan-administered Kashmir is set to produce 4,500 megawatts of power, aimed at overcoming major electricity shortages in the region.
