The Dalai Lama has been a controversial figure for decades. Earlier Thursday, China's foreign ministry accused him of using a trip to Latin America to promote Tibetan secession from China.
In a statement, a foreign ministry spokesman said the Dalai Lama is not a purely religious figure but a political exile engaged in activities designed to split China. The spokesman urged Latin American nations to be - in his words - on "high alert" for what he called the Dalai Lama's secessionist activities.
The Dalai Lama is currently wrapping up a Latin American tour that has included stops in Brazil, Peru, and Colombia.
