I certainly don't believe the US has such a policy. So, it surprises me when people think other countries have such a policy. Never has such a thing happened in the history of the world.
learn history. China was a textbook quality isolationist when it was the biggest economy in the world. it doesn't have any peaceful globalism policy because trading with the rest of the world was simply banned.
