If you control the populace's view of the outside world then you can turn foreigners into anything you want them to be: monsters, war mongers, greedy capitalists intent on collapsing your economy and taking away the dream of prosperity, etc. China has too many single men who will never know marriage and who present a huge threat to their society.
