José Antonio Kast visited Buenos Aires and met Javier Milei, saying Chile will support any effort that ends Venezuela's "narco-dictatorship" after winning Chile's presidency with 58.1 percent.He excluded direct Chilean intervention, called the Venezuelan crisis a "gigantic problem" that fuels migration, and said regional leaders discussed opening humanitarian corridors to return migrants, citing United Nations figures.Kast ran a hardline campaign promising tougher crime and immigration measures, pledged to cut about $6 billion within 18 months while keeping social benefits, will be sworn in on March 11 next year, and faces a fragile economy and likely resistance from Congress and the courts.
