The US plans to stop some Chinese students from coming to study. This makes it difficult for these students to continue their studies in the US. The US is doing this to students who study important subjects or have connections to the Chinese government. Many students from China study in the US. China is not happy about this decision and says it is unfair. This problem has made the relationship between the two countries worse. Because of this, some Chinese students are now choosing to study in other places, like Hong Kong, which are giving them new chances.
