China is a large economy but it's nothing like the dominant force many people seem to think. China is 16% of US trade, 22% of EU trade, 22% of Japan's trade, 22% of South Korea's trade, etc... the numbers are the same for just about everyone.
If you add up all the West-aligned countries (including Vietnam, Philippines, etc - they're already in a cold war with China over the South China Sea), you're looking at 80-90% of China's total trade volume.
Without some kind of major political split in the dollarized world, China just doesn't have that kind of leverage. We're currently seeing the opposite of that split.
