Chinese intelligence operations in the United States mean that the Chinese government is trying to find out secret and important information about the United States. They do this by spying, which means they try to get secrets without people knowing. They could use different methods, like hacking into computer systems, listening to people's conversations, or even having people in the United States working for them. China is trying to find out information like what American leaders are planning, how the American economy is doing, or how to make the Chinese military stronger. By doing this, the Chinese government can gain an advantage over the United States.
