LA PAZ, Jan. 14 (Xinhua) -- Bolivian Foreign Minister Rogelio Mayta has denounced a tweet written by a U.S. government official on the situation in the Santa Cruz department, saying the remarks constitute an interference in the internal affairs of his country.
"Comments of this type are not appropriate in international relations. Relations between states are carried out based on the principle of mutual respect and non-interference. It can be understood from that perspective that this tweet can be interpreted as interference," Mayta told a press conference in La Paz on Friday.
U.S. Undersecretary of State for Western Hemisphere Affairs Brian Nichols recently expressed his "concern" over the arrest of Santa Cruz's governor and opposition leader, Luis Fernando Camacho, in late December.
According to the state-run Bolivian Information Agency, Mayta said the matter will be raised with the charge d'affaires of the U.S. diplomatic delegation in La Paz.
In 2008, Bolivia expelled the U.S. ambassador over allegations that he was inciting the political opposition, a move the United States reciprocated.
Camacho was apprehended on Dec. 28 and later transferred to La Paz, where he has been placed in detention after being accused of terrorism over his participation in the "coup d'etat" that led to the resignation of Evo Morales as president.
