US imposes 5% tariff on Chinese solar panel cells

Trade tensions between the world's two largest economies, the United Stares and China, have risen with the decision by Washington to impose tariffs of nearly 5% on Chinese manufacturers of solar panel cells.

The move follows a review by the US Commerce Department which in a preliminary decision claims that Chinese firms are benefiting from unfair export subsidies.
