The company, Skyline, will also grow and process fruit on site.
Samoa's Prime Minister Tuilaepa Sailele Malielegaoi said he welcomed Skyline's development because it would create jobs.
"With 200 new employees at the factory plus an additional 100 new employees to work at the proposed farm, that would plant the various crops of nonu, sour-sop, avocado, breadfruit and other fruit trees."
Skyline plans to send up to 25 containers of product to China each month.
Last year, it shipped nearly $US4 million worth of noni juice to China.
