Rioja, Spain's most famous wine producing region, is to open commercial offices in Mexico, Germany, the US and Poland during 2002, the Spanish press reported today, in an effort to boost business from the region abroad.

The plan has been drawn up by the Agencia de Desarollo Economico Riojana (ADER) and Spain's Instituto de Comercio Exterior (ICEX).

The first of the offices - which will operate out of existing government trade delegation facilities - is tipped to open in Mexico City.
