The new policies that President Trump has enacted to weigh down imports from places like China risk not only a trade war but real conflict between the two global powers, holds Gideon Rachman of the Financial Times. The two countries have long been bound by strong economic ties. At a time when issues like disputes over an island in the South China Sea are causing tension, hampering trade could worsen relations significantly. Trade is one of the last strong ties that the two countries share. A rising China and a growingly isolationist US are big threats to the current balance of peace. Trump should be cooperating with China and help it develop.
