World trade deep problems

Here is an evident proof of deep problems in world trade. It consists of
few tables (follow links).
Problems in international trade mean a wide range of social and political
challenges. Trade drop in perspective leads to GDP fall, because of import
substitution is the issue of time, so internal demand does not find an
immediate supply so retail (for example) is in a big trouble, while export
drop (and this is much more important) means problems to GDP value (falling
of the number of certain kind goods produced in the country). China's
import collapse means problems for countries all around the World, because
of its highly diversified trade connections. It is analogically in the
cause of the USA, Japan, Germany etc.
