Chinese exporters have reported a surge in demand for quick-frozen chopped onions from European countries, with export volumes expected to rise by 40-50% from May to October. This increase is attributed to last year's drought in Europe, which has heightened the demand for quick-frozen vegetables. As a result, European countries are purchasing large quantities of quick-frozen onions and carrots from China, while the prices for these vegetables on the international market are experiencing a significant uptick.
