In a statement, the ministry said Mahathir is scheduled to meet Philippine President Rodrigo Duterte during his visit on Wednesday and Thursday.
The BOL is the result of the decades-long, on-and-off peace negotiations between the Philippine government and the Moro Islamic Liberation Front (MILF), the country's largest Muslim rebel group.
"Malaysia has been a staunch supporter of the Mindanao peace process and is honored to play a constructive role as the third-party facilitator in the peace process to ensure greater safety and stability in the Philippines and the region," the ministry said.
It said "The visit will provide opportunities for both leaders to further strengthen bilateral relations and cooperation between the two countries.
The Philippines is Malaysia's fourth largest trading partner among the Association of Southeast Asian Nations (ASEAN) countries with the total trade between the two growing from 5.93 billion U.S. dollars in 2017 to 6.45 billion dollars in 2018.
The ministry added that the visit was expected to add momentum to the peace process in southern Philippines after the government passed the Bangsamoro Organic Law (BOL) in January, on the creation of a larger autonomous Bangsamoro region in southern Philippines.
"It would also allow Malaysia to highlight the government's current policies and its stand particularly on issues of mutual concern."
KUALA LUMPUR, March 5 (Xinhua) -- Malaysian Prime Minister Mahathir Mohamad will pay a two-day working visit to the Philippines, the Malaysian Foreign Ministry said on Tuesday.常熟锦湖路
