During his visit, Khan is scheduled to separately meey Chinese President Xi Jinping and Premier Li Keqiang, reports Dawn news.
Khan will discuss expansion of projects under the China-Pakistan Economic Corridor (CPEC) and cooperation in the agriculture, industrial and socio-economic sectors.
Last week, Khan said that the removal of all bottlenecks in CPEC projects and their timely completion was the top priority of the government.
Amid a perceived slowdown on CPEC, the federal Minister for Planning, Development and Reforms Makhdum Khusro Bakhtyar on Sunday said Pakistan would engage China at the highest level for talks on several big projects in the fields of hydropower, oil refinery and steel mills.
During the premier's visit, the two sides will discuss the "immediate implementation" of the second phase of the China-Pakistan free trade agreement (FTA), Dawn reported.
They will also discuss the abolition of the quota for all Pakistani agro products.
The prime minister is also expected to address the China Pakistan Business Forum in Beijing and to meet with Chinese entrepreneurs as well as the heads of different companies, Radio Pakistan reported.
This is the premier's third visit to China since he came to power in August 2018.
In April, he visited Beijing to attend the second Belt and Road Forum and for talks with the Chinese leadership on the expanded CPEC. His first official visit was in November 2018.
