The United States continues to support Tokyo's plan to hold the Summer Olympics, with an expectation of strict protocols to protect visiting athletes amid the coronavirus pandemic, the White House said Tuesday, a day after the State Department issued an advisory against traveling to Japan.

"Our position has not changed on the Olympics," White House press secretary Jen Psaki told a news conference, noting the Japanese government's assurances that "public health remains the central priority" in plans for hosting the games.

The United States sent ripples across Japan by raising its travel advisory to the Asian country to the highest level of 4 on Monday due to a rise in coronavirus cases, just two months before the start of the Tokyo Olympics.
