On 29 Aug 1842 The Treaty of Nanking signed aboard Cornwallis. The peace treaty that concluded the First Opium War. The Chinese regarded it as an 'Unequal Treaty'; the British fleet were anchored in Nanking poised to attack. The treaty required the Chinese to pay the British six million silver dollars for the opium that had been confiscated by Lin Zexu in 1839 (Article IV), 3 million dollars in compensation for debts that the Hong merchants in Canton owed British merchants (Article V), and a further 12 million dollars in war reparations for the cost of the war (Article VI). The total sum of 21 million dollars was to be paid in instalments over three years and the Qing government would be charged an annual interest rate of 5 percent for the money that was not paid in a timely manner (Article VII) (See Wikipedia).
