Despite being a powerhouse in past international competitions, China is currently experiencing a surprising downturn in its medal acquisition, notably lacking any gold medals. The underperformance has caught international attention, and raised speculations regarding China's sports infrastructure.
As Japan is a neighboring country and a co-competitor in international sports, any developments regarding China's sports performance is of interest. The values involved here include sportsmanship, national pride and competitiveness. The Japanese audience largely tracks medal tallies, which form a significant part of their interest in international sports events.
Tracking national teams' performance and medal counts during international sports events is common in both the EU and US, much like in Japan. Underperformance by any country with a strong track record in sports, like China, would likely receive media attention and public speculation in these regions as well.
