The European Commission launched an investigation on Thursday into Chinese Peking duck after several EU producers complained of unfairly low prices harming their industry.

Without disclosing their names, the Commission said that five EU producers had complained that China is unfairly subsidising domestic production via its five-year plan for agricultural modernisation.

The probe comes at a time of heightened tensions between Beijing and Brussels, as the EU seeks to shield its market from cheap Chinese imports, triggering Beijing's ire as it aims to preserve access to the lucrative European market.

After China repeatedly threatened retaliation over several EU legislative proposals restricting access to EU public procurement and setting strict conditions on foreign investment, the two sides started negotiations last week to ease tensions.

However, the EU's latest move targeting duck imports could disrupt the talks by hitting China's agricultural sector for the first time.
