Brown made the announcement after meeting with Chinese Vice President Xi Jinping in Los Angeles Friday.
Tim Robertson with the California Fair Trade Coalition says the meeting and announcement are encouraging. He hopes they lead to a narrowing of the state's $100 billion trade imbalance with China.
ROBERTSON: "We're concerned about the way China behaves as a trading partner through currency manipulation, lowered wages and environmental standards, and mercantilistic practice. In General, we're very concerned that what we're going to see is a much larger increase in imports than we do in exports."
Brown says China could provide more than $2 trillion in investments in the United States within the next ten years.
The trade offices will be in Beijing and Shanghai.
