Advantage West Midlands spent more than £30,000 wining and dining guests at this year's MIPIM international property fair in the South of France, according to figures released by the regional development agency.
Bills paid by AWM at the four-star La Croissette restaurant in Cannes included:
* £10,928 for a drinks reception and dinner;
* £8,625 for a cocktail party and £2,469 for three business breakfasts;
* A welcome barbecue at £4,406 and a launch party at £3,868.
The events, in March, were attended by developers and property experts from Europe and across the world.
By comparison, Birmingham City Council spent £450,000 on an exhibition, entertaining and travel at MIPIM.
AWM also spent £60,000 on an ICT conference at the National Motorcycle Museum in Solihull, £15,000 to stage an environmental conference at the NEC and £21,710 to hold six consultative events on the West Midlands Economic Strategy.
Details of expenditure for the 2006-07 financial year for all of the English Regional Development Agencies were released following a Freedom of Information Act request by Liberal Democrat MP Norman Baker.
Mr Baker accused the agencies of being "cavalier with taxpayers' money" and demanded an inquiry by the National Audit Office.
He said: "No elected politician would get away with this and there is no reason why obscure, unelected, unaccountable officials should either."
An AWM spokesman defended the agency's expenditure at MIPIM, which he described as the "number one global land and property show". The spokesman added: "It is a unique opportunity for Advantage West Midlands to provide a powerful voice for the many public and private sector partners - from North Staffordshire to Herefordshire - who see it as essential that we are showcased on this platform.
"The tremendous backing we receive each year from our partners shows how important they see this opportunity and we help them make the most of it.
"It is our chance to not only showcase what the region has to offer but also network with key contacts at what is possibly the largest gathering of international intermediaries in the business calendar including influential figures from inward investment, commercial property and the business and professional services.
"Our breakfast meetings and drinks receptions are held to connect regional partners with many of those leading players - essential when you consider global competition in commercial property development is growing in intensity.
"We are not just competing against cities such as Manchester Bristol. We are in competition on a world stage against Budapest, Prague, Beijing and Boston."
The payments were relatively small in comparison to expenses incurred by other regional development agencies.
The chairman and chief executive of the South-east England Development Agency spent almost £70,000 on taxis and private hire cars, while a two-day staff event at Center Parcs cost the South-west of England RDA £61,600.
In total during 2006/07, AWM spent £298,394 organising 19 conferences and events. Almost half of the total - £140,673 - went on the agency's annual conference at the ICC in June.
The agency also spent £759,000 maintaining offices in Japan, France, Germany, Brussels, Sweden and America. Foreign trips by 123 members of staff cost £50,859 in air fares, with the single most expensive ticket a Virgin Atlantic Airways return for one person from Heathrow to Washington at a cost of £3,158.
Travel expenses claimed by AWM chairman Nick Paul included £1,302 for mileage and £374 for taxis. Chief executive John Edwards claimed £1,201 for mileage, £672 for taxis and £827 for other unspecified expenses.
