Crown Prince Felipe told international investors on Tuesday that now is the "best time" to take advantage of business opportunities that are opening up in Spain as the Iberian nation adopts the necessary measures to resume growing economically.

"We're facing the problems ... (and) our economy's needs for transformation," he said at the opening of Spain Investors Day in Madrid.

"Of course, it's an enormous and also delicate task that needs the participation of society and public and private institutions," the prince said.

The two-day event gathers together a significant number of entities from all over the world along with Spain's main companies.

Prince Felipe listed among the strengths of the Spanish economy the growth of competitiveness and the diversification of exports.

In addition, he noted that the Spanish market represents a quarter of the eurozone with 47 million consumers and that it receives more than 57 million tourists annually.

Spain also offers access to 1.3 billion consumers thanks to its geographic location and its historical and cultural links with many countries around the world.

Spanish firms in sectors such as infrastructure, energy, textiles and finance are among the leading companies in the world, the prince emphasized. EFE
