It doesn't seem to me like the rest of the world is united against China. Even the US companies and universities are very friendly with them.
Universities get these students to pay full tuition. Professors get graduate workhorses for research. Companies get cheap labor, low environmental standards, etc so they get a larger profit margin on their widget.
China does have a sphere of influence but the total population of china + friends is well below 3 billion people and will continue to drop as a percentage of the world population.
