Taiwan's Executive Yuan Premier expressed his gratitude towards the Kaohsiung City Mayor. Though specifics aren't offered, the headline suggests the Mayor potentially offered some form of support or compromise beneficial to Taiwan's administration. In Japan, such an action would be seen as an important gesture of goodwill between the two countries.

In Japan, cross-strait relations between Taiwan and mainland China are closely observed. As Japan has a complex and sensitive relationship with both, diplomatic actions like this would be seen as significant. The fact that the Premier of Taiwan publicly thanked a Japanese mayor underscores the importance of mutual understanding and cooperation in regional politics.

In the US or EU, similar instances of international diplomatic acknowledgements would also be closely examined. However, the context differs, as the US and the EU are larger players in international politics with different vested interests. Still, such a gesture from a high-ranking official would signify an endorsement and potential strengthening of diplomatic ties.
