China on Tuesday warned the European Union that EU firms would suffer if it decides to take action against companies in China\'s solar and telecommunications sectors due to trade rows. EU firms have long accused Beijing of giving Chinese solar cell makers and telecoms firms an unfair competitive advantage through state subsidies, and have called for Brussels to restrict imports of their products. The European Union is reportedly preparing to launch an anti-dumping investigation into leading Chinese telecoms firms Huawei and ZTE. Commerce ministry spokesman Shen Danyang rejected allegations that the two companies received subsidies as \"groundless\", adding they have been growing through \"complete market competition\". He pointed out that many European telecoms companies have operated in China for many years, benefiting both Beijing and Brussels. \"China does not want such a win-win situation being undermined or damaged,\" he said. \"Facing the grave world economic situation, we think China and the EU should enhance policy coordination... and refrain from using trade protection measures.\"(QNA)
