That accords with Duterte's aspirations at home. Having waged a war on drugs and vowed to make peace with the rebels, he pledges to spur economic development for the benefit of all the Philippine people.

For Duterte's domestic visions to materialize, Manila needs international supporters, not least those who sympathize with his fierce campaign against drugs and stand ready to increase investment in his country.

Beijing will be a ready partner should bilateral ties thaw. China has expressed understanding of Duterte's priority on the antinarcotics battle, and the world's second-largest economy is also interested in tapping into the two countries' respective strengths and cranking up win-win cooperation.

The benefits of the anticipated rapprochement go beyond the two countries. It is a win for all peace-loving and development-pursuing nations in the region, as it will spare the region of contagious tensions and help foster a conducive neighborhood environment.

Without doubt, it is pure fantasy to expect the visit to solve all problems between China and the Philippines. Yet the very fact that the trip happens is indicative of the spunk and statecraft of both sides, and suffices to bring forth optimism and hope.
