Hi @lu ren ,
Welcome to Q&A forum!
Generally, if you can sign in and access OneDrive normally, its response speed will be affected by the computer bandwidth and network.
But according to my research, local legal restrictions will determine whether you can access data in OneDrive abroad. And sometimes, you may have to choose to work offline with OneDrive.
Besides, since we are more focused on general issues about OneDrive client (including deployment, installation, and troubleshooting like file synchronization), I suggest you contact Microsoft Support directly to confirm this issue.
Hope the information is helpful to you.
