"Chile does not spy," Carolina Toha, a spokeswoman for Chile's Interior Ministry, said Saturday. "Chile takes international relations as a serious matter."
Peruvian President Alan Garcia left the Asia-Pacific Economic Cooperation summit in Singapore Saturday and returned to Peru after reports of the alleged espionage surfaced, CNN reported Sunday.
Garcia had been scheduled to attend a workshop Saturday in Singapore with Chilean President Michelle Bachelet and other world leaders.
The suspect air force officer was "under arrest and in the hands of the judicial power in Peru" Saturday, Chilean Foreign Minister Jose Antonio Garcia Belaunde said from Singapore.
"We do consider, from the information that we have received, that we need an explanation and sanctions to those involved," Belaunde said, adding he had yet to hear "all the elements of the story."
