Explanation:

The Treaty of Nanjing was signed on August 29, 1842  in the waters of Nanjing aboard the British warship HMS Cornwallis. These negotiations (later called Unequal Treaties) were carried out after the defeat of China (under the Qing Dynasty) by the British Empire in the context of the so called "First Opium War" that began in 1839 and ended in 1842.

In this context, diverse policies were signed (mainly in favor of the British Empire), however the three remarkables ones were:

- British citizens on Chinese soil gained immunity from prosecution under Chinese law.

- The  opening of four Chinese ports to foreign trade alongside Canton (Shameen Island) having a total of five ports where foreign merchants were to be allowed to trade: Amoy (Xiamen), Foochowfoo (Fuzhou), Ningpo (Ningbo) and Shanghai.

-The creation of the crown colony of Hong Kong after the Chinese Emperor ceded this island to the British Queen.

several states had passed similar laws, but they were limited to intrastate businesses. the sherman antitrust act was based on the constitutional power of congress to regulate interstate commerce.
