From Quiz The Phoenix Regenerates in Peru
Answer:
Chile
The Republic of Peru (República del Perú) lies on South America's central western coast on the Pacific Ocean, where its coastline measures 2,414 km (1,500 mi). It is the 19th largest country in the world by area, and the third largest in the continent after Brazil and Argentina.
The land borders total 7,461 km (4,636 mi). To the north are Ecuador (1,420 km/882 mi) and Colombia (1,800 km/1,118 mi). Brazil lies to the east (2,995 km/1,861 mi), with Bolivia southeast (1,075 km/668 mi).
Chile, with the shortest border (171 km/106 mi), is south of Peru. The two countries have shared a relationship since the times of the 15th-century Incan Empire. Once both countries achieved independence from Spain in the 19th century, relations have fluctuated from peace to wars and subsequent treaties. In 2009 a Peru-Chile Free Trade agreement came into force.
Brazil is a full member of the Mercosur Southern Common Market (1991), a South American trade bloc. The other countries mentioned in this question - Peru, Chile, Colombia and Ecuador - are associated members, while Bolivia is transitioning to full membership.
