Mexican President Felipe Calderon met with Spain's King Juan Carlos I during the 4th Alliance of the Pacific Summit in the northern Chilean city of Paranal, the Office of the President said in a statement.

Calderon, who is attending the summit as a special guest, praised the "intensity" of the high-level Mexican-Spanish political dialogue, citing Spanish Prime Minister Mariano Rajoy's visit to Mexico in April as an example of the extensive bilateral contacts.

The Mexican president and King Juan Carlos discussed the challenges faced by the global community in light of the economic situation in Europe during their meeting on Wednesday.

Calderon and King Juan Carlos agreed that the upcoming G-20 meeting offered an opportunity for the world's leading economies "to find joint and coordinated responses for creating a more efficient common front," the statement said.

The Mexican president expressed concern about immigration rules implemented in Spain that have affected Mexican tourists and called for "an alternative to the situation being encountered by Mexicans traveling to Madrid," the statement said.

Calderon and King Juan Carlos discussed Mexico's participation in the celebration of the bicentennial of the Spanish Constituion of 1812, as well as the celebration of the 35th anniversary of the restoration of diplomatic relations between Mexico and Spain.

Foreign Relations Secretary Patricia Espinosa also participated in the meeting.

The Foreign Relations Secretariat, meanwhile, said in a statement that Mexico and Spain agreed to hold a meeting before the end of this month to address the immigration rules imposed by the European country.

The rules have caused some Mexican travelers to be barred from entering Spain on arrival at airports.

Espinosa and her Spanish counterpart, Jose Manuel Garcia Margallo, "reiterate their firm willingness to find a satisfactory solution to the problems that may have been produced, contributing to facilitating the entry and transit of Mexican tourists." EFE
