Bolivia's President Evo Morales has met with Peruvian presidential candidate Ollanta Humala ahead of Peru's upcoming presidential runoff election.

The meeting between the two leftist political leaders took place Monday in the Bolivian town of Copacabana near the Peruvian border. Mr. Morales invited Mr. Humala to attend the inauguration of an eye clinic in the town, funded by money from Cuba.

Cuban President Fidel Castro's government has been training Bolivian eye doctors to provide treatment at the new clinic.

Hundreds of Bolivians greeted Mr. Morales and Mr. Humala at the ceremony, chanting revolutionary slogans and waving Cuban and Bolivian flags.

Mr. Humala said the meeting would strengthen Latin American integration, and said it was a natural reflection of Peru's and Bolivia's shared history.

Mr. Humala is campaigning for Peru's presidential run-off election on June fourth, when he will face former Peruvian President Alan Garcia. Mr. Humala has promised to increase state control over Peru's natural resources if elected.
