Yangtze incident, was a historic event that occurred on the Yangtze River for three months in the summer of 1949, during the late phase of the Chinese Civil War. The incident involved the Communist People’s Liberation Army (PLA), who were in the process of a river-crossing offensive to overthrow the Nationalist Government, and four British Royal Navy ships HMS Amethyst, HMS Black Swan, HMS Consort and HMS London. The British warships, whose claimed right of passage along the Yangtze had been unchallenged previously since the 1858 Treaty of Tientsin with the late Qing dynasty, came under bombardment by PLA artillery and were forced to withdraw permanently from Chinese territorial waters.
The incident was described in the British press as a dramatic escape, while it has been widely celebrated in the People’s Republic of China as a milestone incident that marked the end of Western gunboat diplomacy in China and as one of the last nails in the coffin for the Century of Humiliation
Margaret Thatcher entered negotiations for the future of Hong Kong with significant confidence bolstered by the British victory in the Falklands War (1982). This victory increased her domestic prestige and encouraged a firmer stance in international dealings, including with China.
Coming only three months after the Falklands victory, Thatcher’s September 1982 visit to Beijing was seen as an opportunity to project strength and uphold British treaty rights regarding Hong Kong. Before negotiation, Margret thatcher had good confidence that she could extend the lease , but during the negotiation Deng emphasized that China would definitely take back Hong Kong, with or without British agreement.
According to memoir recollections on hongkong negotiation , Deng xioping told thatcher that :----------->
“” Congratulations on the Falklands, but don’t think that could happen in Hong Kong.” “I could send peoples liberation army to roll over hongkong in this afternoon if you don’t agree , Sovergnity is non negotiable”
Thatcher replied to Deng that :--------------> “There is nothing I could do to stop you, but world would see how china behaves and hongkong would collapes"
thatcher describing the 1982 meeting :(From The Irish Times (1996)) “Deng was “short-tempered, bossy, " and very tough to negotiate .”
Unlike the Falklands, which could be defended militarily by a naval task force, Hong Kong was geographically vulnerable, bordering mainland China and china have a large sized army with over a million troops . Despite having Hong Kong Island and Stonecutters Island which is Ceded to Britain in perpetuity under the Treaty of Nanjing (1842) and Convention of Peking (1860). UK gave up sovergnity on entire hongkong .
The handover of Hong Kong from the United Kingdom of Great Britain and Northern Ireland to the People’s Republic of China occurred at midnight on 1 July 1997. This event ended 156 years of British rule, dating back to the cession of Hong Kong Island in 1841 during the First Opium War.
Handover of hongkong was done by an agreement with agreement for protection of democracy in hongkong . But most political observors claim that by the indroduction of "The Fugitive Offenders and Mutual Legal Assistance in Criminal Matters Legislation (Amendment) Bill 2019 " defacto marked end of assured democracy under sino British agreement.
