That Xi is receiving Modi on the same day as the leaders of North and South Koreas hold talks has raised eyebrows, but analysts view the timing as coincidental and not meant to overshadow the inter-Korean summit, especially considering the difficulties in scheduling and preparing for meetings between any senior leaders.
"Xi has had his meeting with (North Korean leader) Kim Jong Un," said Duncan Innes-Ker, regional director for Asia at the Economist Intelligence Unit (EIU), suggesting people not read too much into the timing "given that the Chinese side has lined up its ducks when it comes to the coming Korean summit, and India is only tangentially interested and involved in the Korean situation at best."
'Unprecedented changes'
"As the leaders of the two largest developing countries, they feel that the two countries need to communicate in great depth on some long-term, comprehensive and strategic issues embedded in bilateral relations and international affairs," Chinese Foreign Ministry spokesman Lu Kang told reporters Tuesday.
It's no coincidence that Lu chose to underscore that the meeting, the Indian Prime Minister's fourth in China, would take place "in the face of unprecedented changes in the world today."
As a result, improving weak economic ties are likely to be a top priority within any attempt to reset bilateral relations.
Although China is India's largest trading partner, their $84 billion bilateral trade last year was a mere fraction of the US-China trade volume, which stood almost $600 billion.
"Realistically, China's exports to India are not going to offset any impact that might have come from a China-US trade war," said Innes-Ker.
"China needs access to the India market, where the Indian government has been slapping tariffs on them and imposing non-tariff barriers," he said. "It's in China's interest to get these economic issues resolved."
"If you're not friendly with China, the US -- especially under Trump -- will finish you off and give you a very bad bargain," said Madhav Das Nalapat, director of the geopolitics department at Manipal University in India. "If you're not friendly with the US, China will roll over you."
"So if you want a healthy relationship with China or the US, you need healthy relations with both," he added. "We need the US on security and China for commerce and trade."
Major strategic divergences
Both countries boast ancient civilizations and centuries-old ties. But in recent years, China and India have had a rocky relationship. Last summer's Himalayan standoff was the latest in a long-running series of territorial flare-ups between the two nuclear powered neighbors. In 1962, the two countries engaged in a bloody border war, and skirmishes have continued to break out sporadically in the decades since.
At a press conference in March, Chinese Foreign Minister Wang Yi said the two countries' leaders "have developed a strategic vision for the future of our relations: the Chinese 'dragon' and the Indian 'elephant' must not fight each other, but dance with each other."
Analysts appear divided on such a prospect under two strong nationalistic leaders, even though many see the two men get along well at a personal level despite the vastly different political systems of their countries.
"This is a recognition of both leaders that India and China are going to have to work together in order to make the 21st Century the Asian century," said Nalapat, the Indian professor. "The Asian century, frankly, is at the core of this summit."
"They are going to work hard on creating a very strong relationship, on creating oxygen that can pour down and help solve problems at the lower level," he added.
"There is a huge difference between having a relatively positive personal relationship and having a productive strategic relationship," said Innes-Ker of the EIU.
"The underlying story is that this remains an antagonistic relationship and the strategic tensions will far outweigh any common ground that they find between each other."
