The book of art of war duterte knows it that is why he play in international arena in the whole world. To get what he wants for the better future of the Philippines. Unlike before Philippines will be soon rise in the sky. I hope people in the Philippines listen to this leader. I hope they will not corrupt in their respective agency.
I doubt his policies will bring in big investors like China had happen during the 90's. Those are two completely different countries.
What does the Philippines have that the US may want? Cheap labor is all I can come up with. They already have china for that..
