针对美国商务部长骆家辉的批评，中国为其外国投资环境辩护。骆家辉已被提名担任下一任美国驻华大使。
这次言语交锋发生在下周举行的美中战略与经济对话举行之前。骆家辉星期三在华盛顿表示，中国公司在美国享有的机会多于美国公司在中国的机会，这种不平衡是改善贸易关系的“一个重大障碍”。
但是，外交部发言人姜瑜星期四在北京的记者会上坚持说，外国公司在中国享有平等待遇。姜瑜说，外国企业应凭自身实力在中国取得成功。
China is defending its foreign investment climate in the face of critical comments from Gary Locke, the U.S. commerce secretary who has been nominated to be the next U.S. ambassador in Beijing.
The exchange comes ahead of annual high-level talks next week known as the U.S.-China Strategic and Economic Dialogue. Locke said Wednesday in Washington that Chinese companies enjoy more opportunities in the United States than American firms do in China, and that the imbalance is a “major barrier” to improved commercial relations.
But at a briefing Thursday in Beijing, foreign ministry spokeswoman Jiang Yu insisted that foreign companies enjoy equal treatment in China. She challenged them to rely on their own strength for success in that country.
