MADRID, April 13 (Xinhua) -- World Cup champion Spain has declined an invitation to replace Japan at this summer's Copa America.

The Spanish football federation said on its website that a board of directors meeting decided not to send a team at the July 1-24 tournament in Argentina due to "conflicts with the calendar."

The federation said a dense schedule of fixtures makes the World Cup and European champion's participation "impossible".

Japan withdrew last week because of the devastating earthquake and tsunami that struck the country on March 11.
