evidence: Jilin[a] is one of the three provinces of Northeast China. Its capital and largest city is Changchun. Jilin borders North Korea (Rasŏn, North Hamgyong, Ryanggang and Chagang) and Russia (Primorsky Krai) to the east, Heilongjiang to the north, Liaoning to the south, and Inner Mongolia to the west. Along with the rest of Northeast China, Jilin underwent an early period of industrialization. However, Jilin's economy, characterized by heavy industry, has been facing economic difficulties with privatization. This prompted the central government to undertake a campaign called "Revitalize the Northeast". The region contains large deposits of oil shale. [...] The region then fell successively under the domination of the Xiongnu, Xianbei state, Goguryeo, Balhae, Khitan Liao Dynasty, the Jurchen Jin Dynasty, and the Mongol Yuan dynasty.[8] During the Qing Dynasty, much of the area was under the control of the General of Jilin (Girin i Jiyanggiyūn), whose area of control extended to encompass much of what is Russia's Primorsky Krai today. [...] The province is rich in large reserves of oil, gas, coal, iron, nickel, molybdenum, talc, graphite, gypsum, cement rock, gold and silver; its reserves of oil shale are the largest in the country.[11]
