What happened when China appealed to the league of nations to stop the invasion?

When China appealed to the League of Nations to stop the Japanese invasion in the early 1930s, particularly during the Mukden Incident in 1931, the League conducted an investigation and ultimately condemned Japan's actions. However, the League's inability to enforce its decisions or impose effective sanctions rendered its response largely ineffective. Japan withdrew from the League in 1933, further undermining the organization's authority and highlighting its limitations in addressing aggression among member states. This failure marked a significant moment in the League's history and foreshadowed the broader conflicts leading to World War II.
