Sham Chun River
In May 1995, the governments of Hong Kong and Shenzhen jointly completed the environmental impact assessment study of the Sham Chun River Stage 1 works (), which comprised the construction of two new, wider and deeper river sections of about 3.2 km long at Lok Ma Chau and Liu Pok () to replace existing river bends. The governments of Hong Kong and Shenzhen were committed to implementing a comprehensive environmental monitoring and audit programme.
