In the latest effort to tighten travel restrictions to limit the spread of the novel coronavirus, President Trump has ordered the closure of the border between the U.S. and Mexico to all but essential travel. This move follows an announcement earlier this week that both America and Canada agreed mutually to close their shared border to non-essential travel for at least 30 days, while it remains open for urgent, necessary business and commercial traffic.

Trump had also already taken steps to minimize border crossing at the Mexican border, taking additional steps to block migrants and asylum seekers on top of what measures are are already in place, as reported by CNN earlier this week. The U.S. also issued a “do not travel” warning to its own citizens on Thursday, which broadly advises against traveling to any international destination. Trump has also said that internal travel restrictions are not out of the question pending the pandemic’s progress.
