The only reason why the Marshall plan worked is because there was a world war and nearly everybody in Europe decided "not again". Other countries have not made this experience and for them military conflict (or threat of conflict) is still a valid and legitimate way to protect their interests and expand their sphere of influence (see China and the South China sea). What worked in one place will not necessarily work elsewhere. In fact, I think it's already proven to not have worked in the case of China. Despite the amount of money flowing into the country over the past 2 decades, their ambition and their tension with their neighbors have only grown. They're on their way to becoming a military superpower as well.
