For example, Chinese nationals can enter our country and gather information on our infrastructure, corporations, and people with relative ease because English is prevalent, and foreign nationals have, with the exception of certain military/research areas, the same access that US citizens have. On the other hand, foreign nationals in China are closely monitored and have very few rights, assuming they know Chinese, are physically in China (Great Firewall), and know how to get around in the first place.

China has unfettered access to our media ecosystem, research, patents, etc., and they do their best to create an uncompetitive/hostile environment for any other country to attempt the same on their territory. Some of this has to do with trade—to be fair, these are intertwined—but the situation regarding intelligence is bleak.
