European Union countries approved an agreement with China to curb imports of Chinese solar panels, ending the EU’s biggest commercial dispute of its kind.

EU governments endorsed an accord struck by their trade chief and China in July that sets a minimum price and a volume limit on European imports of Chinese solar panels until the end of 2015. Chinese manufacturers that take part will be spared EU tariffs meant to counter alleged below-cost sales, a practice known as dumping, and subsidies.

The verdict seeks to balance demands by European producers such as Solarworld AG (SWV)for trade protection and opposition by China, some EU governments and Europe’s importers to levies on the renewable-energy technology. The two-year duration of the measures is less than half as long as the normal five-year period for EU anti-dumping and anti-subsidy protection.

European solar-panel manufacturers suffered “material injury” as a result of dumping by Chinese exporters and trade-distorting government aid to them, while trade protection must also take account of “the cost for other economic operators,” the 28-nation bloc said today in Brussels. The decision wraps up two inquiries begun more than a year ago and will take effect after being published in the EU’s Official Journal by Dec. 6.
