PM Modi and President Xi will share a moonlight dinner tonight in a Swiss luxury tent on the banks of the river Sabarmati. Xi will be treated to a 150-dish Gujarati banquet and will also join PM Modi on a walk down the riverfront. (In PM Modi's Gujarat, 'Khaman' and 'Dhoklas' for Chinese President)
The Chinese president's visit comes in the middle of a new face-off at the border after more than 200 soldiers of the People's Liberation Army reportedly crossed into Indian territory in Ladakh earlier this week and set about building a 2-km road at the Chumur sector.

India is also expected to raise another point of contention - China's policy of issuing stapled visas to Indians from Arunachal Pradesh. Sources say India may assert that China must recognise a "one India policy". As the row continues, the two countries will not sign a deal today to liberalise Visas to China for business.

The two leaders are, however, expected to sign pacts on infrastructure and railways.
On Tuesday, PM Modi said the relationship between the two countries "goes beyond plain arithmetic", and summed up ties with a new mantra - "Inch (India and China) towards Miles (Millennium of Exceptional Energy)." ('Inch Towards Miles': PM Modi's Take On Ties With China Before Xi Visit)

In a sign that India wants the Xi visit to be a success, New Delhi has reportedly asked Tibetan spiritual leader the Dalai Lama to reschedule an event so that it would not clash with the Chinese president's trip to the capital.
Recently, during a visit to Japan, Mr Modi was seen to have taken a swipe at China when he said foreign policy based on expansionism and maritime incursions are the signs of "18th-century" thought.
