If you apply in China, you will only get rights protection in mainland China (except Hong Kong, Macao and Taiwan). For example: if you have not applied for it in the United States, then Americans can implement your patent without your consent. Then there is a problem.

When entering the national phase, you can choose to enter in these countries. If you go through If you select a country for authorization, your patent will receive protection in that country. The cost of this kind of PCT application is very high. The international stage is okay. The cost after entering the national stage is quite high. Generally, a country needs at least 100,000 yuan.
