No different to what they are facing now and their expansion the last 30 years.
Over the last 30 years China has grown an average of 10% a year. To keep things sustainable for employment etc they need to growth 8% a year and the policies of the government will align with this.
It's also to illustrate a point that the economy will surpass the US within the next 5 years an they will continue to invest around 2% of GDP in military spending and there is no reason not to continue this.
