The EU’s anti-dumping and anti-subsidy measures imposed on China’s solar panel products carried special significance for China-EU economic and trade relationships. The EU’s investigation was launched in September 2012 and met firm protests from China. This case became white-hot in the first half of 2013. China had hoped to reach a price-undertaking solution through negotiations，in order to avoid being imposed with high anti-dumping tax which could be devastating for China’s PV industry. However，the EU wished to take the advantage of the Solar Panel case to press China to further open its market. At the end，the two sides successfully reached a deal on price-undertaking and solved appropriately the biggest trade dispute in the history of China-EU trade and economic relationships. At the same time，China and the EU announced officially the start of the negotiation on a China-EU investment agreement，which will promote the further development of the bilateral economic and trade relationships.
