The European Commission has launched an investigation into its trade agreement with China that imposed a minimum import price (MIP) on PV modules and components. The price is benchmarked against Bloomberg spot prices, which SolarWorld-led trade body EU ProSun has claimed is unsuitable.Last week EU ProSunsaid it planned to lodge a complaint. However, the focus of the complaint is not the existing trade tariffs but the functioning of the negotiated agreement between Chinese manufacturers and the Commission.At the heart of the review request is the alleged rush of Chinese companies to register prices since the MIP was established. In addition, the Commission published the decision to initiate the review in its official register on May, 5. It has 15 months to conclude its investigation and the current trade duties were set to expire in seven months.
