BOGOTA/QUITO, Jan 22 - Colombia will suspend electricity sales to Ecuador and impose a 30% tariff on 20 products from its neighbor, it said on Thursday, in an escalating dispute over trade and the fight against drug trafficking.

The move came a day after Ecuador's President Daniel Noboa said his government would impose a 30% "security charge" on goods from Colombia, starting on February 1, citing a trade deficit and a lack of cooperation on fighting drug trafficking.
