Moon's visit will only be the second time Biden has hosted another world leader in-person since taking office in January. The normal flurry of visits that accompany the early weeks of a new presidency was absent this year due to the Covid-19 pandemic. The first, Japanese Prime Minister Yoshihide Suga, came last month. Hosting Japan first -- as former President Donald Trump did -- and South Korea second, is a clear indication the new President and his advisers view the Asia Pacific region as their biggest long-term priority overseas.
Biden's secretaries of state and defense have already visited both Tokyo and Seoul. Military leaders from the three countries met in Hawaii in late April. And White House national security adviser Jake Sullivan hosted his Japanese and South Korean counterparts shortly before that.
