State-run Global Times, part of the ruling Communist Party of China's People's Daily publication group, said in an editorial that the Sino-Indian cooperation is "invaluable".
"The geopolitical significance of the benign development of Beijing-New Delhi ties can't be duplicated," said the daily known for its nationalistic views.
"The better China-India relations develop, the more advantages and initiatives India can have when dealing with the US and Japan."
"A positive New Delhi-Beijing engagement would force Washington and Tokyo to cosy up to India," it said.

Xi is the first leader of a major power to visit India after the Narendra Modi-led government took charge, it said. His first stop is in Prime Minister Modi's home state of Gujarat on Modi's 64th birthday.
Referring to Modi's recent visit to Japan, the daily said the "floods of rhetoric such as 'joining hands to counter China' emanated from Japanese public opinion to which Modi gave a rational response at the time."
"Now it seems that this mentality from many Japanese is very wide of the mark."
China has a long-term strategy for a friendly cooperation with India, rather than seeking short-term gains, it said adding that "for us, the Sino-Indian relationship, with its own strategic merits, doesn't have to be associated with ties with other major powers."
"We need to discover more of the common interests between the two countries which will have a stunning purchasing power upon humanity's future," it said.
