This is the 62-year-old leader's first visit to Beijing after she took over the office last year.
Swaraj is expected to finalise arrangements for opening the second route of the Kailash-Manasarovar Yatra in Tibet for which China agreed last year to open it for Indian pilgrims.
The route through Nathu La Pass in Sikkim which facilitates comfortable travel by buses through Tibet was expected to be opened in the next few months.
Swaraj is accompanied by new Foreign Secretary S Jaishankar, among other senior ministry officials.
This is Jaishankar's first foreign trip after being appointed two days back, replacing Sujatha Singh whose tenure was abruptly "curtailed".

He served as India's Ambassador to China for nearly four years before being appointed as Ambassador to the US in 2013.
During the trip, that comes within a week of US President Barack Obama's three-day visit to New Delhi, Swaraj will "discuss bilateral, regional and global issues of concern to both sides" with her Chinese counterpart Wang Yi, Ministry of External Affairs said in New Delhi yesterday.
The two sides will also explore the possibility of a visit by Prime Minister Narendra Modi later this year.
Swaraj is also expected to meet Xi, who along with Wang, had visited India last year immediately after the installation of the Modi government.
During her stay here, Swaraj will speak at the India- China Media Forum, interact with the Indian Community of Beijing (ICB) and inaugurate the 'Visit India Year' aimed at attracting more Chinese tourists to India.
