Document 4: Handover of Hong Kong: The transfer of sovereignty over Hong Kong, commonly known as the handover of Hong Kong (or simply ``the Handover '', also`` the Return'' in mainland China) was the transition of control over the former British colony of Hong Kong from the United Kingdom to the People's Republic of China on 1 July 1997. The returned territory comprised Hong Kong Island and the Kowloon Peninsula, which were respectively ceded to Britain in 1842 and 1860, as well as the New Territories, which were leased for 99 years from 1898. The transfer was arranged to coincide with the expiration of this lease on the previous day, 30 June 1997.

Document 7: Macau: Macau was formerly a colony of the Portuguese Empire, after Ming China leased the territory as a trading post in 1557. Originally governing under Chinese authority and sovereignty, Portugal was given perpetual occupation rights for Macau in 1887. Macau remained under Portuguese control until 1999, when it was returned to China. As a special administrative region, Macau maintains a separate political and economic system apart from mainland China.
Document 8: Portugal: In 1986, Portugal joined the European Economic Community (EEC) that later became the European Union (EU). In the following years Portugal's economy progressed considerably as a result of EEC/EU structural and cohesion funds and Portuguese companies' easier access to foreign markets.
Document 9: Euro: The euro is the sole currency of 19 EU member states: Austria, Belgium, Cyprus, Estonia, Finland, France, Germany, Greece, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Portugal, Slovakia, Slovenia, and Spain. These countries constitute the "eurozone", some 343 million people in total as of 2018.With all but two of the remaining EU members obliged to join, together with future members of the EU, the enlargement of the eurozone is set to continue. Outside the EU, the euro is also the sole currency of Montenegro and Kosovo and several European microstates (Andorra, Monaco, San Marino and the Vatican City) as well as in five overseas territories of EU members that are not themselves part of the EU (Saint Barthélemy, Saint Martin, Saint Pierre and Miquelon, the French Southern and Antarctic Lands and Akrotiri and Dhekelia). Together this direct usage of the euro outside the EU affects nearly 3 million people.
Document 10: Portugal: The Portuguese currency is the euro (€), which replaced the Portuguese Escudo, and the country was one of the original member states of the eurozone. Portugal's central bank is the Banco de Portugal, an integral part of the European System of Central Banks. Most industries, businesses and financial institutions are concentrated in the Lisbon and Porto metropolitan areas—the Setúbal, Aveiro, Braga, Coimbra and Leiria districts are the biggest economic centres outside these two main areas.[citation needed] According to World Travel Awards, Portugal is the Europe's Leading Golf Destination 2012 and 2013.
Document 11: Macau: Macau was administered by the Portuguese Empire and its inheritor states from the mid-16th century until late 1999, when it constituted the last remaining European colony in Asia. Portuguese traders first settled in Macau in the 1550s. In 1557, Macau was leased to Portugal from Ming China as a trading port. The Portuguese Empire administered the city under Chinese authority and sovereignty until 1887, when Macau became a colony through a mutual agreement between the two countries. Sovereignty over Macau was transferred back to China on 20 December 1999. The Joint Declaration on the Question of Macau and Macau Basic Law stipulate that Macau operate with a high degree of autonomy until at least 2049, fifty years after the transfer.
Document 12: Portugal: In 2007, Portugal had 10,617,575 inhabitants of whom about 332,137 were legal immigrants. In 2015, Portugal had 10,341,330 inhabitants of whom about 383,759 were legal migrants, making up 3.7% of the population. In 2017, Portugal had 416,682 legal residents of foreign origin, of which 203,753 identified as male, and 212,929 as female.Portugal's colonial history has long since been a cornerstone of its national identity, as has its geographic position at the south-western corner of Europe, looking out into the Atlantic Ocean. It was one of the last western colonial European powers to give up its overseas territories (among them Angola and Mozambique in 1975), turning over the administration of Macau to the People's Republic of China at the end of 1999. Consequently, it has both influenced and been influenced by cultures from former colonies or dependencies, resulting in immigration from these former territories for both economic and personal reasons. Portugal, long a country of emigration (the vast majority of Brazilians have Portuguese ancestry), has now become a country of net immigration, and not just from the last Indian (Portuguese until 1961), African (Portuguese until 1975), and Far East Asian (Portuguese until 1999) overseas territories. An estimated 800,000 Portuguese returned to Portugal as the country's African possessions gained independence in 1975.Since the 1990s, along with a boom in construction, several new waves of Ukrainian, Brazilian, Lusophone Africans and other Africans have settled in the country. Romanian, Moldovans, Kosovar and Chinese have also migrated to the country. Portugal's Romani population is estimated to be at about 40,000. Numbers of Venezuelan, Pakistani and Indian migrants are also significant.
Document 13: Euro: The euro is managed and administered by the Frankfurt-based European Central Bank (ECB) and the Eurosystem (composed of the central banks of the eurozone countries). As an independent central bank, the ECB has sole authority to set monetary policy. The Eurosystem participates in the printing, minting and distribution of notes and coins in all member states, and the operation of the eurozone payment systems.
Document 14: Portugal: Portugal lost much of its wealth and status with the destruction of Lisbon in a 1755 earthquake, occupation during the Napoleonic Wars, and the independence of Brazil, its wealthiest colony, in 1822. After the 1910 revolution deposed the monarchy, the democratic but unstable Portuguese First Republic was established, later being superseded by the "Estado Novo" right-wing authoritarian regime. Democracy was restored after the Portuguese Colonial War and the Carnation Revolution in 1974. Shortly after, independence was granted to all its colonies, with the exception of Macau, which was handed over to China in 1999. This marked the end of the longest-lived European colonial empire, leaving a profound cultural and architectural influence across the globe and a legacy of over 250 million Portuguese speakers today.
