Following a briefing by the National Intelligence Service, the lawmaker talked about the completion of Pyongyang’s preparations for a nuclear test, adding they're only looking for the right time. Meanwhile, the United States has warned that a possible nuclear test could happen while President Joe Biden is in Seoul this week. This is going to be Biden's first trip as president to Asia. And the US intelligence says it's possible that North Korean Leader Kim Jong-un would stage a provocation after Biden arrives in Seoul late Friday. The U-S and North Korea have been locked in a standoff over Pyongyang’s missile and nuclear tests, which the White House describes as provocative. But the North argues it needs them to protect itself from America.
