During Chinese Leader Xi Jinping's latest visit to North Korea, the presence of Kim Jong-un's sister, Kim Yo-jong remains undetected. Known for her increasing influence in North Korean politics, her absence has caught the attention of international observers and spurred speculations. The reasons behind her absence are yet undetermined.

Japanese observers are paying attention to this development due to its implications for regional politics. Changes in North Korean leadership, or speculation thereof, can have profound effects on Japan's diplomatic strategy towards North Korea. Politicians and media often delve into these minute details to predict future diplomatic scenarios.

In the US or EU, similar issues would be followed closely considering North Korea's nuclear program and human rights record. They would be discussed in journalistic circles and think tanks, but the general public might not be as involved in the speculation as the Japanese due to geographical proximity and direct security concerns.
