BELGRADE — The international system that has brought unprecedented prosperity to the world since 1945 is based on rules that apply without exception. This system is supposed to protect the basic, legitimate national interests of every country, whether rich or poor, strong or weak. Its binding principles include the sovereign equality of states, the respect for the territorial integrity and the inviolability of internationally recognized borders.

Yet on Feb. 17, the Serbian province of Kosovo, which has been under United Nations administration since 1999, unilaterally declared independence from my country. This illegal act has, unfortunately, been recognized by the Bush administration and some European countries including Britain, France and Germany. Others in Europe — including Greece, Romania and Spain — have withheld recognition, as have most other leading global and regional players, including Brazil, China, Egypt, India, Israel, Russia and South Africa.

As things stand, the number of countries that will recognize an independent Kosovo will plateau at around 40, leaving it unrecognized by a vast majority of the close to 200 members of the United Nations. This includes, of course, The Republic of Serbia.
