After that, when the regime of Wang Zhaoming was established during the second Sino-Japanese War of 1937-1945, Japan, which defended the regime, considered the abrogation of the unequal treaty, the Treaty on Basic Relations between Japan and China was concluded on November 30, 1940 and the unequal treaty was formally abrogated (however, the presence of Japanese troops in China was accepted in the treaty, and the Japan-Manchukuo-China Joint Declaration which practically recognized Manchukuo was concluded at the same time, as a result, the hostility of the Chinese people toward the regime of Wang Zhaoming increased).
その後、日中戦争下で汪兆銘政権が成立すると、同政権を擁護する立場から不平等条約破棄が検討され、1940年11月30日に日華基本条約が結ばれて不平等条約は正式に破棄された（ただし、この条約で日本軍の中国国内への駐留が認められ、また満州国を事実上承認する日満華共同宣言が併せて締結されたことから、汪兆銘政権への中国国民の反感を高める結果となっている）。
