In a unique diplomatic gesture, Japanese politicians served the renowned 'Ishiba-style' curry to President Lee. Known for its distinctive taste and origin as a politician's home recipe, the curry was presented as a culinary representation of the cordial relations between Japan and President Lee's nation. This diplomatic event aimed to strengthen bilateral ties and encourage mutual understanding, while also settling any political differences over a friendly, informal meal.

In Japan, food is often used as a soft power tool to foster good relationships and further diplomatic goals. This event exemplifies Japan's emphasis on maintaining cordial relationships and using unconventional avenues like food to bridge political gaps. Given the popularity of the 'Ishiba-style curry' in Japan, it's seen as a friendly gesture that resonates with the public.

In the US and EU, similar efforts are made to promote diplomacy through cultural exchange. This often includes serving local delicacies or hosting meals at renowned restaurants. However, the preparation and serving of a dish by a political figure themselves, as is the case in Japan, is less common.
