NYT: U.S. Excluded From EU's Coronavirus 'Safe' Traveler Lists

The EU is considering blocking US travelers due to the US's handling of the COVID-19 pandemic. Draft lists suggest allowing China but excluding the US, Russia, and Brazil. This decision could impact Europe's economy, as many Americans visit each summer. The list will be updated bi-weekly based on infection rates. The EU cannot enforce the list, but non-compliance may lead to internal border issues. The US has the highest COVID-19 cases globally, with recent increases attributed to more testing. Previously, the US restricted EU travelers, and these restrictions remain.
