Isolationism in the context of "Neutral country"

Sakoku (Japanese: 鎖国; IPA: [sa̠ko̞kɯ̟]; lit. 'chained country') was the isolationist foreign policy of the Japanese Tokugawa shogunate under which, during the Edo period (from 1603 to 1868), relations and trade between Japan and other countries were severely limited, and almost 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.

Japan was not completely isolated under the sakoku policy. Sakoku was a system in which strict regulations were placed on commerce and foreign relations by the shogunate and certain feudal domains (han). There was extensive trade with China through the port of Nagasaki, in the far west of Japan, with a residential area for the Chinese. The policy stated that the only European influence permitted was the Dutch factory at Dejima in Nagasaki. Western scientific, technical and medical innovations flowed into Japan through Rangaku ("Dutch learning").

South Korea, officially the Republic of Korea (ROK), is a country in East Asia. It constitutes the southern half of the Korean Peninsula and borders North Korea along the Korean Demilitarized Zone, with the Yellow Sea to the west and the Sea of Japan to the east. Like North Korea, South Korea claims to be the sole legitimate government of the entire peninsula and adjacent islands. It has a population of about 52 million, of which half live in the Seoul metropolitan area, the ninth most populous metropolitan area in the world; other major cities include Busan, Daegu, and Incheon.

The Korean Peninsula was inhabited as early as the Lower Paleolithic period. Its first kingdom was noted in Chinese records in the early seventh century BC. From the mid first century BC, various polities consolidated into the rival kingdoms of Goguryeo, Baekje, and Silla. The lattermost eventually unified most of the peninsula for the first time in the late seventh century AD, while Balhae succeeded Goguryeo in the north. The Goryeo dynasty (918–1392) achieved lasting unification and established the basis for the modern Korean identity. The subsequent Joseon dynasty (1392–1897) generated cultural, economic, and scientific achievements and also established isolationism starting from the mid-17th century. The succeeding Korean Empire (1897–1910) sought modernization and reform but was annexed in 1910 into the Empire of Japan. Japanese rule ended following Japan's surrender in World War II, after which Korea was divided into two zones: the Soviet-occupied northern zone and the United States-occupied southern zone. After negotiations on reunification failed, the southern zone became the Republic of Korea in August 1948, while the northern zone became the communist Democratic People's Republic of Korea the following month.

The Edo period, also known as the Tokugawa period, is the period between 1600 or 1603 and 1868 in the history of Japan, when the country was under the rule of the Tokugawa shogunate and some 300 regional daimyo, or feudal lords. Emerging from the chaos of the Sengoku period, the Edo period was characterized by prolonged peace and stability, urbanization and economic growth, strict social order, isolationist foreign policies, and popular enjoyment of arts and culture.

In 1600, Tokugawa Ieyasu prevailed at the Battle of Sekigahara and established hegemony over most of Japan, and in 1603 was given the title shogun by Emperor Go-Yōzei. Ieyasu resigned two years later in favor of his son Hidetada, but maintained power, and defeated the primary rival to his authority, Toyotomi Hideyori, at the Siege of Osaka in 1615 before his death the next year. Peace generally prevailed from this point on, making samurai largely redundant. Tokugawa shoguns continued Ieyasu's policies of conformity, including a formalization of social classes in a strict hierarchy. By 1639, all foreigners were expelled under the policy of sakoku, with the exception of Dutch traders on the island of Dejima in Nagasaki, beginning a period of isolation. From 1635, daimyō had to spend alternating years in the capital Edo, where their family was required to reside permanently, in a system of "alternate attendance" in order to keep them in check.

Sovereigntism, sovereignism or souverainism (from French: souverainisme, pronounced [suvʁɛnism] ) is the notion of having control over one's conditions of existence, whether at the level of the self, social group, region, nation or globe. Typically used for describing the acquiring or preserving political independence of a nation or a region, a sovereigntist aims to "take back control" from perceived powerful forces, either against internal subversive minority groups (ethnic, sexual or gender), or from external global governance institutions, federalism and supranational unions. It generally leans instead toward isolationism, and can be associated with certain independence movements, but has also been used to justify violating the independence of other nations.

From 1910 to 1945, Korea was ruled by the Empire of Japan as a colony under the name Chōsen (朝鮮), the Japanese reading of "Joseon".

Japan first took Korea into its sphere of influence during the late 1800s. Both Korea (Joseon) and Japan had been under policies of isolationism, with Joseon being a tributary state of Qing China. However, in 1854, Japan was forcibly opened by the United States. It then rapidly modernized under the Meiji Restoration, while Joseon continued to resist foreign attempts to open it up. Japan eventually succeeded in forcefully opening Joseon with the unequal Japan–Korea Treaty of 1876.

Gojong (Korean: 고종; Hanja: 高宗; 8 September 1852 – 21 January 1919), personal name Yi Myeongbok (이명복; 李命福), later Yi Hui (이희; 李㷩), also known as the Gwangmu Emperor (광무제; 光武帝), was the penultimate Korean monarch. He ruled Korea for 43 years, from 1864 to 1907, first as the last king of Joseon, and then as the first emperor of the Korean Empire from 1897 until his forced abdication in 1907. His wife, Queen Min (posthumously honored as Empress Myeongseong), played an active role in politics until her assassination carried out by the Japanese.

Gojong oversaw the bulk of the Korean monarchy's final years. He was born into the ruling House of Yi, and was first crowned on 13 December 1863 at the age of twelve. His biological father, Grand Internal Prince Heungseon (widely known as Heungseon Daewongun), acted as regent until he reached the age of majority, although he continued holding power until 1874. At this time, Korea was under policies of strict isolationism. By contrast, Japan had been rapidly modernizing under the Meiji Restoration. In 1876, Japan forcefully opened Korea and began a decades-long process of moving the peninsula into its own sphere of influence. For the following few decades, Korea was highly unstable, and subjected to a number of foreign encroachments. Incidents such as the 1882 Imo Incident, the 1884 Kapsin Coup, the 1894–1895 Donghak Peasant Rebellion, and the 1895 assassination of Gojong's wife occurred during his reign. All of these incidents were related to or involved foreign powers.

Nanban trade (南蛮貿易, Nanban bōeki; "Southern barbarian trade") is the European trade in Japan between the arrival of Europeans in 1543 to the first Sakoku Seclusion Edicts of isolationism in 1614.

International development or global development is a broad concept denoting the idea that societies and countries have differing levels of economic or human development on an international scale. It is the basis for international classifications such as developed country, developing country and least developed country, and for a field of practice and research that in various ways engages with international development processes. There are, however, many schools of thought and conventions regarding which are the exact features constituting the "development" of a country.

Historically, development was largely synonymous with economic development, and especially its convenient but flawed quantification (see parable of the broken window) through readily gathered (for developed countries) or estimated monetary proxies (estimated for severely undeveloped or isolationist countries) such as gross domestic product (GDP), often viewed alongside actuarial measures such as life expectancy. More recently, writers and practitioners have begun to discuss development in the more holistic and multi-disciplinary sense of human development. Other related concepts are, for instance, competitiveness, quality of life or subjective well-being.
