The US President recently made a statement aiming to restrain China over the issue related to Taiwan, creating a ripple effect on global politics. The pointed words underscore the brewing tension amidst the longstanding mainland-Taiwan conflict. This stern stance from the US President not only highlights America's support for Taiwan but also connotes a veiled warning to China for its assertive actions in the region.

Given its geographical proximity and economic ties, Japan has a keen interest in maintaining stability in the region. Greater tension between China and Taiwan could lead to potential economic disruptions or even outright conflict, which would pose a risk to both Japan's national security and its economy. Good relations with both countries are of paramount importance to Japan.

US and EU often echo similar concerns regarding China's assertiveness towards Taiwan. While the US is more overt and vocal in its support for Taiwan, the EU tends to approach it from a more diplomatic angle, emphasizing more on peaceful dialogue and conflict resolution.
