Sanctions are ineffective because it is very difficult to unify an adequate number of countries to cripple an economy.  Many countries must employ sanctions for them to be successful, yet due to competing political objectives unifying enough countries is almost impossible. If sanctions are only imposed by a few countries, the sanctioned nation can replace lost trade from those countries with trade from other allies, deflecting the economic consequences of the sanctions. North Korea is so isolated from the international community that sanctions have had little effect, particularly because their most important trade partner, China, has continued to do business with them1. The UK and US sanctions have not been effective in the case of Myanmar given that the country mainly trades with other ASEAN member states, India, China and Japan. The violation of sanctions often has to do with political motives. In the case of ASEAN, the member countries are concerned that China may use Myanmar for military and naval bases, so they are pouring money into the country and breaking US sanctions to promote their own self-interest in the region and counter China2. Considering that every country has their self-interest in mind, it is ultimately too difficult to forge a united front between enough countries to cripple the country they are sanctioning. 1 Noland, Marcus (2009), "The (Non-) Impact of UN Sanctions on North Korea", The National Bureau of Asian Research, [Accessed June 10, 2011]. 2 Heritage Foundation (1997), "A User's Guide To Economic Sanctions", , [Accessed June 10, 2011].
