Final answer:
The unequal treaties established extraterritoriality, set low import and export duties, and allowed for freedom of religion, significantly impacting the sovereignty and cultural landscape of Asian nations like China and Japan.
Step-by-step explanation:
The signing of the unequal treaties with Western powers led to several significant consequences for the countries involved, particularly in Asia. For example, China was forced to sign treaties that granted extraterritoriality to foreigners, meaning they were exempt from local law and subject to the laws of their own country while in China.
These treaties also set low import and export duties, favoring the economic interests of Western nations, and allowed freedom of religion in the foreign settlements, which introduced new cultural influences. Additionally, countries like Japan had to accept the division of territories after the Treaty of Versailles, reflecting the European powers' sphere of influence expanding into Asia.
