The treatment of foreign investment in China is determined by the activity or sector to which it is addressed. There are several sectors that are totally restricted to foreign investment or to which the foreign investor can only access through a mixed capital company.
In the field of infrastructures, China lacks a law that regulates investment models by concession. However, some provinces do have some published guidelines. In general, access to the activity of design and construction of transport infrastructures in China is hampered by barriers of access and notable local competition. This activity is, for the moment, accessible to foreigners essentially when local companies can not do so or when it comes to preliminary design.
