根据下面资料，回答题 In January 1995, the world witnessed the emergence of a new international economic order with the launchingof the World Trade Organization. The WTO, which succeeds the GATT, is expected to strengthen the world tradingsystem and to be more effective than the GATT in governing international trade in goods and services in many as-pects.
First, trade liberalization all over the world is expected to increase via the dramatic reductions in trade barriers towhich the members of the WTO are committed. Under the WTO, members are required to reduce their tariff and non-tar-iffs on manufacturing goods. In addition, protecting domestic agricultural sectors from foreign competition will becomeawfully difficult in the new WTO system.
Second, rules and regulations governing international trade will be more strongly enforced. Under the old sys-tem of the GATT, there were many cases where trade measures, such as anti-dumping and countervailing duties,were intentionally used solely for protectionist reasons. The WTO's strengthened rules and regulations will signifi-cantly reduce the abusing of such trade measures by its member countries. The WTO is also equipped with animproved dispute settlement mechanism. Accordingly, we expect.to see a more effective resolution of trade disputesamong the member countries in this new trade environment.
Third, new multilateral rules have been established to cover areas which the GATT did not address, such as in-temational trade in services and the protection of intellectual property rights. There still remain a number of problemsthat need to be resolved before international trade in services can be completely liberalized, and newly-developed ide-as or technologies are fairly compensated. However, just the establishment of multilateral roles in these new areas isa distinguished contribution to the progress toward a global free trade system.
Along with the launching of the WTO, this new era in world trade is characterized by a change in the structureof the world economy. Today, a world-wide market for goods and services is rapidly replacing a world economycomposed of relatively isolated national markets. Domestic financial markets have been integrated into a truly globalsystem, and the multinational corporation is becoming a principal mechanism for allocating investment capital anddetermining the location of production sites throughout much of the world.

B．WTO is the pre-existence of GATT
C．GATT is the pre-existence of WTO
