Opium WarsThe Opium Wars ( Yāpiàn zhànzhēng) were two conflicts waged between China and Western powers during the mid-19th century. The First Opium War was fought from 1839 to 1842 between China and the United Kingdom, and was triggered by the Chinese government's campaign to enforce its prohibition against opium trafficking by British merchants. The Second Opium War was waged by Britain and France against China from 1856 to 1860.
Border controlBorder control refers to measures taken by governments to monitor and regulate the movement of people, animals, and goods across land, air, and maritime borders. While border control is typically associated with international borders, it also encompasses controls imposed on internal borders within a single state. Border control measures serve a variety of purposes, ranging from enforcing customs, sanitary and phytosanitary, or biosecurity regulations to restricting migration.
International zoneAn international zone is any area not fully subject to the border control policies of the state in which it is located. There are several types of international zones ranging from special economic zones and sterile zones at ports of entry exempt from customs rules to concessions over which administration is ceded to one or more foreign states. International zones may also maintain distinct visa policies from the rest of the surrounding state.
Extraterritorial jurisdictionExtraterritorial jurisdiction (ETJ) is the legal ability of a government to exercise authority beyond its normal boundaries. Any authority can claim ETJ over any external territory they wish. However, for the claim to be effective in the external territory (except by the exercise of force), it must be agreed either with the legal authority in the external territory, or with a legal authority that covers both territories. When unqualified, ETJ usually refers to such an agreed jurisdiction, or it will be called something like "claimed ETJ".
International watersThe terms international waters or transboundary waters apply where any of the following types of bodies of water (or their drainage basins) transcend international boundaries: oceans, large marine ecosystems, enclosed or semi-enclosed regional seas and estuaries, rivers, lakes, groundwater systems (aquifers), and wetlands. "International waters" is not a defined term in international law. It is an informal term, which sometimes refers to waters beyond the "territorial sea" of any country.
Enclave and exclaveAn enclave is a territory (or a small territory as part of a larger one) that is entirely surrounded by the territory of one other state or entity. Enclaves may also exist within territorial waters. Enclave is sometimes used improperly to denote a territory that is only partly surrounded by another state. Vatican City and San Marino, both enclaved by Italy, and Lesotho, enclaved by South Africa, are completely enclaved sovereign states.
Treaty portsTreaty ports (; 条約港) were the port cities in China and Japan that were opened to foreign trade mainly by the unequal treaties forced upon them by Western powers, as well as cities in Korea opened up similarly by the Japanese Empire. List of Chinese treaty ports The British established their first treaty ports in China after the First Opium War by the Treaty of Nanking in 1842. As well as ceding the island of Hong Kong to Great Britain in perpetuity, the treaty also established five treaty ports at Shanghai, Guangzhou (Canton), Ningbo, Fuzhou, and Xiamen (Amoy).
International lawInternational law (also known as public international law and the law of nations) is the set of rules, norms, and standards generally recognised as binding between states. It establishes normative guidelines and a common conceptual framework for states across a broad range of domains, including war and diplomacy, economic relations, and human rights. International law differs from state-based domestic legal systems in that it is primarily, though not exclusively, applicable to states, rather than to individuals, and operates largely through consent, since there is no universally accepted authority to enforce it upon sovereign states.
Sakokuwas the isolationist foreign policy of the Japanese Tokugawa shogunate under which, for a period of 265 years during the Edo period (from 1603 to 1868), relations and trade between Japan and other countries were severely limited, and nearly all foreign nationals were banned from entering Japan, while common Japanese people were kept from leaving the country. The policy was enacted by the shogunate government (bakufu) under Tokugawa Iemitsu through a number of edicts and policies from 1633 to 1639, and ended after 1853 when the Perry Expedition commanded by Matthew C.
JoseonJoseon (; tɕo.sʌn), officially Great Joseon (; tɛ.tɕo.sʌn.ɡuk̚), was the last dynastic kingdom of Korea, lasting just over 500 years. It was founded by Yi Seong-gye in July 1392 and replaced by the Korean Empire in October 1897. The kingdom was founded following the aftermath of the overthrow of Goryeo in what is today the city of Kaesong. Early on, Korea was retitled and the capital was relocated to modern-day Seoul. The kingdom's northernmost borders were expanded to the natural boundaries at the rivers of Amrok and Tuman through the subjugation of the Jurchens.
