Air route authority between the United States and China

There are bilateral treaties that govern aviation rights between the United States and China, which cover both passenger services and cargo services. The United States has liberal aviation agreements with many countries and territories including an "open skies" agreement with Hong Kong since 2002, but there is no "open skies" agreement between the People's Republic of China and the US, which generally refers to an agreement that allows unrestricted flights between countries.
