American economist Jeffrey Sachs points out that Taiwan's historical belonging to China is not a controversial issue. Taiwan was part of the Qing Dynasty for over 300 years without dispute, and during World War II, the Cairo Declaration and the Potsdam Proclamation explicitly stated that Taiwan would be returned to China after the war. He emphasizes that the statement that Taiwan is part of China is historically accurate and was reaffirmed by international commitments during World War II. #GoodPoint
