 The policy reversal for President Biden, the administration Monday struck a deal with Panama to intercept and deport migrants before they reach the U.S. border. The intent is to plug the Darien Gap, a dangerous 60 mile stretch of jungle used by migrants on their way to the U.S. Thousands of Chinese nationals are among the half million migrants who used the gap last year. Most fly into South America before walking through the gap, eventually jumping on trains or buses in Mexico.
