• an enormous burden of premature cardiovascular disease

• low awareness, poor control and limited resources

• evidence-based clinical guidelines for the management of hypertension and cardiovascular disease well established, but not implemented in rural areas

Main Challenges in Prevention and Control of Chronic Disease in China

• Financing and resourcing health system for prevention and control of none-communicable diseases should be well included as an important component of future urbanization plan of China.
