From a NY Times article about Chinese production of solar panels, here are several trade issues that arise:
Subsidies
Since March, Chinese governments at the national, provincial and even local level have been competing with one another to offer solar companies ever more generous subsidies, including free land, and cash for research and development. State-owned banks are flooding the industry with loans at considerably lower interest rates than available in Europe or the United States.
Buy America and Foreign Investment
The American economic stimulus plan requires any project receiving money to use steel and other construction materials, including solar panels, from countries that have signed the World Trade Organization’s agreement on free trade in government procurement. China has not.
In response to this, and to reduce shipping costs, Suntech plans to announce in the next month or two that it will build a solar panel assembly plant in the United States, said Steven Chan, its president for global sales and marketing.
“It’ll be to facilitate sales — ‘buy American’ and things like that,” Mr. Chan said, adding that the factory would have 75 to 150 workers and be located in Phoenix, or somewhere in Texas.
Anti-Dumping
Even with Suntech acknowledging that it sells below the marginal cost of producing each additional solar panel — that is, the cost after administrative and development costs are subtracted — any antidumping case, in the United States, for example, would have to show that American companies were losing money as a result.
