The European Union has warned that it will drag India to the World Trade Organisation if New Delhi fails to slash taxes on wines and spirits imported from Europe. Spokesperson for the EU Agriculture and Rural Development Michael Mann told Indian journalists visiting the EU headquarters in Brussels that they are trying to negotiate with India on the wines and spirit issue. India had in 2007 slashed the additional customs duty but simultaneously hiked the basic customs duties to 150 per cent from 100 per cent.

The European Commission had earlier taken India to WTO in 2007 seeking redressal of its grievances which included what it called denial of 'national treatment' to liquor imported from Europe. Under the national treatment rules, the imported products have to be treated at par with domestic items
