I believe China's strategy is to allow foreign business to operate to a certain extent to provide a competitive impetus to their local favored companies. Basically I think their strategy is, inside China the foreign company will be allowed to have a market share of 20% to 50%, if it exceeds that they will create obstacles, as their own preferred (i.e. Chinese controlled) companies figure out how to compete.
Once it is competitive they will subsidize it (via. redistribution from financial repression of lower & middle class individuals to below market financing of businesses, and compliant regulation i.e. no unions, lax pollution) to give it an advantage to gain market share globally.
Regarding immigration, they already have a huge labor supply and if they need more I think they will prefer to do it by exporting their political and managerial apparatus, rather than importing bodies. For example their investments in Africa, and Australia: https://www.nytimes.com/2017/06/06/world/australia/china-pol... .
