Wadar - Last year, Saudi offered Pakistan a $6 billion package that included help to finance crude imports.
Beijing has pledged $60 billion as part of the China Pakistan Economic Corridor (CPEC) that involves building power stations, major highways, new and upgraded railways and higher capacity ports, to help turn Pakistan into a major overland route linking western China to the world.
"With setting up of an oil refinery in Gwadar, Saudi Arabia will become an important partner in CPEC," Pakistan Petroleum Minister Ghulam Sarwar Khan said.
The Saudi news agency SPA earlier reported that Falih met Pakistan's petroleum minister and Maritime Affairs Minister Ali Zaidi in Gwadar to discuss cooperation in refining, petrochemicals, mining and renewable energy.
It said Falih would finalise arrangements ahead of signing memorandums of understanding.
Since the government of Prime Minister Imran Khan came to power in August, Pakistan has secured economic assistance packages from Saudi Arabia and China.
In November, Pakistan extended talks with the International Monetary Fund as it seeks its 13th bailout since the late 1980s to deal with a looming balance of payments crisis.
