The move is the latest by China to revive tourism and boost the world's second-largest economy following a slump during the COVID-19 pandemic. Tourist visa applicants in the U.S. will no longer need to submit air ticket bookings, hotel reservations or an invitation letter, the embassy's notice said. Visa-free treatment will run for 12 months, during which tourists from those six countries can visit China for up to 15 days. The number of inbound tourists to the country plummeted during the pandemic due to the country's strict COVID control policies. International flights to China have picked up since Beijing dropped COVID restrictions a year ago but are still only at 60% of 2019 levels.
