After Koguryo went south, Kaicheng became the "Winter City" of Baekje, and later Koguryo won the Winter City. The inner city of Kaesong is the city of money, and North Korea is called the imperial city, with thirteen gates. Kaicheng was changed to Song Yue County, a Chinese place name, in the era of unified Silla. In the 16th year of King Jingdezhen (AD 757), it was changed to Kaicheng County. At that time, Kaicheng was originally the fief of local predators, and Wang was one of them. In the 10th year of Silla King (898), Wang Jianzhu, the messenger of Bow Life, sent troops to capture the city. In the fifth year (90 1), the capital of Silla was Koguryo, and in the ninth year (905), the capital was moved to Tieyuan. In 9 19, after Wang Jian was overthrown, Goguryeo ascended the throne and established Korea. The following year (920), the capital moved from Tieru to the south of Song Yue, and the junction of Song Yue and Kaicheng was called Kaizhou. He began to run Wang Du. In 960 (the 11th year of Guangzong), it was renamed the Imperial Capital, and in 995 (the 14th year of Guangzong), it was renamed the Smart City.

10 10 was invaded by Liao and almost completely destroyed. 10 18, the abandoned government was established as a county, which was directly under the jurisdiction of Shangshu and renamed as Gyeonggi. 1024, the capital of Wang Du was rebuilt. In the twentieth year of Xianzong (1028), Luojing was built, with a class of 29,700 and 22 gates, including Chongren, Xu Anqi, Baoding, Guangde, Deshan, Huibin, Xianxi, Taian, Hong Ren, Kande, Baotai, Xuanyi, Sister-in-law and Dingping. There are buildings in the city, such as Shouchang Palace, North Korea Forbidden City, Rende Palace and Shoude Palace.

1062 (16th year of literate Sect) was restored as a government. In the tenth year of King Gongcheng (1360), he gathered people to build the city gate, and in the third year of Qi Xin (1376), he ordered the king to build the capital, and asked him to send five Ding Fu to build the inner city within three years and find it. 1390 (the second year of Gongrang), Gyeonggi was divided into two roads, which belonged to the right.

After the rise of Korea, Lee moved to Hanyang in 1394 (the third year of Taizu) and stayed in the capital, ending the history of Kaicheng as the capital in 489. 1399 restored Kaesong as the king's capital. 1405 moved the capital to Seoul. 1438 changed its name to Kaicheng to stay behind. After several changes, 19 10, after Japan annexed Korea, it was also called Kaichengfu. As the king of Korea, it is the most prosperous. After the Li Dynasty, it became a commercial center. It is famous for its bookkeeping methods and financial records. It is also a famous place of Korean ginseng. The historical relics of Kaesong were destroyed by many wars and almost disappeared. Among the existing ones, the cornerstone of the Moon-gazing Platform at the foot of Song Yue Mountain and Fuyang Academy dedicated to Zheng Mengzhou are the most famous. It is 8 kilometers away from the city. Panmunjom is the name of a village between Kaesong and Seoul. It is said that a small shop was built here with wooden boards a long time ago to facilitate passers-by between Kaesong and Seoul (that is, Seoul), hence the name Panmunjom.

Panmunjom is the venue for negotiation and signing of the Korean armistice, and the meeting rooms of the Military Armistice Commission and the Neutral Nations Supervisory Commission are also located here. On both sides of the military demarcation line in Panmunjom, there are outposts of North Korea and South Korea. Daming Palace, formerly165438+the palace of North Korea in the early 20th century, was once the residence of foreign guests, and was called "Shuntian Pavilion". Later, it was converted into a "monk hall" to promote Confucianism. 1089, imperial academy, the highest institution of higher learning, moved here and changed its name to Sungkyunkwan.

Today, this ancient building has become a "Koryo Museum" showing Korean history, with a large collection of unearthed cultural relics. Kaesong is the light industry center of North Korea. There are jewelry processing factories, Kaesong ginseng processing factories and embroidery factories in the urban area.

In August 2000, Kim Jong Il decided to cooperate with Hyundai Group of the Republic of Korea to open the Kaesong Industrial Zone. North Korea provides land and labor, while South Korea provides capital, technology and electricity. In June 2002, 165438+ 10, North Korea promulgated the Kaesong Industrial Zone Law. In June 2003, the 1 branch began construction, and in 2005, it began to produce some products. South Korean personnel crossed the 38th parallel and entered and exited Kaesong.

It is located about 1 70km south of Pyongyang, 8km south of Kaesong and only1km from the north-south military demarcation line. Kaesong was the capital of the Korean kingdom 600 years ago, and it was rich in ginseng in history.

Kaesong Industrial Park is the product of the 15 * * * Declaration signed in Pyongyang on June 5, 2000 by South Korean President Kim Dae-jung and Chairman of the National Defense Commission of North Korea Kim Jong Il, which symbolizes the good wish of reunification between the North and the South. Based on the principle of the same nation, the Korean side contributed capital and technology, while the DPRK contributed capital and labor, and the two sides cooperated to build an experimental platform for economic unification between the North and the South. The industrial park covers a total area of 65.7 square kilometers with a total investment of 220 million US dollars. The long-term plan is to accommodate 2,000 enterprises, and it is planned to develop in three stages. The first phase of development covers an area of about 3.3 million square meters, which lasted from 2002 to 2007. It mainly attracts Korean small and medium-sized enterprises, mainly producing clothing, shoes and cosmetics. The development area of the second phase of the project is 8.3 million square meters, and the period is from 2006 to 2009, including 4.9 million square meters of industrial parks. Phase II Industrial Park is a technology-intensive industry, mainly producing machinery, electrical appliances and electronic products. The development area of the third phase project is1815000m2, and the period is from 2008 to 20 12 years. The industrial park will develop into a high-tech park focusing on cutting-edge industries such as information and communication. Commercial areas, living areas, tourist areas and logistics centers will be built, and even three golf courses and four theme parks will be built, so that the whole Kaesong area will eventually become a regional economic center. By then, there will be more than 2,000 enterprises,/kloc-0.7 million North Korean workers and an annual output value of 20 billion US dollars, thus laying a solid foundation for the common development of the North and the South and national reunification.

At the beginning of 20 13, due to the tension between the DPRK and the ROK, the Kaesong industrial park was officially closed, and the DPRK and the ROK planned to hold talks to solve the industrial park problem.

On February 1 1, 2065438, the DPRK announced through the statement of the Committee for the Peaceful Reunification of the Motherland that it would expel all the North Korean workers left in the Kaesong Industrial Park at February 16 17 (5: 30 pm Korean time).

The statement said that all assets such as equipment, materials and products of Korean enterprises and related institutions in the industrial zone will be completely seized. In addition to personal belongings, the expelled persons are not allowed to take other articles out of the country, and the seized equipment, materials and products are managed by the people's Committee of the city.
