Wa State
The region is mainly mountainous, with deep valleys. The lowest points are approximately 600 metres above sea level, with the highest mountains over 3000 metres. Initially Wa State was heavily reliant on opium production. With Chinese assistance, there has been a move towards growing rubber and tea plantations. Wa State cultivates 220,000 acres of rubber. Due to the resettlement of residents from mountainous areas to fertile valleys, there is also cultivation of wet rice, corn and vegetables. Dozens died during the resettlement due to disease and road accidents. Wa State is economically dependent on China, which supports it financially and provides military and civilian advisors and weapons. It shares 82 miles (133 km) of frontier with China.
