On Friday, October 1st, North Korea announced that they had test-fired some new anti-aircraft missiles, the fourth recent test. This is after the top U.S., South Korea, and Japan diplomats met to discuss ways in which they could get North Korea to abandon their weapon development. So far the communication line between North and South Korea on both sides is slowly being rebuilt, in order to build a better reputation between the two nations. 

For the Biden administration, they should continue strengthening their bond with the Japanese and South Korean governments. This is especially true for the Japanese government as they just got a new prime minister. I doubt there is much of a difference between this prime minister and the previous’ policies, as they are from the same political party, but it is still important to have a close relationship between the two governments.
