Now, calligraphy heritage, one of the valuable traditional cultural heritages in Korea, is rapidly declining. Even the government is not very interested, and almost the public is only interested. Under these circumstances, in Korea, China, and Japan, where calligraphy culture has historically blossomed, conflicts arise in many areas in terms of cultural identity and cultural sovereignty.In particular, this paper began with China's Northeast Process Project, which is the root of the representative conflict between Korea and China, and examined the current status of the three countries on calligraphy heritage at the cultural sovereignty level. Among them, the Chinese Calligraphy was registered as a UNESCO Intangible Heritage of Humanity in 2008, and from this point of view, we looked at the national and public interest in calligraphy heritage of the three countries, Korea, China, and Japan. Through this, the current status of the Korean calligraphy community was objectively analyzed, and the direction and specific alternatives that the Korean calligraphy community should take in the current situation were presented.China has explicitly incorporated the cultures of 55 minorities in China into its own history in accordance with the unified multi-ethnic state theory since approximately the 1990s. The problem with Korea is related to the Korean-Chinese, and China will carry out the Northeast Process Project. North Korea's application for the listing of the Goguryeo Tombs as a UNESCO World Heritage Site in 2001 served as a decisive opportunity for the Northeast Process. Afterwards, China succeeded in registering the Goguryeo Tombs as UNESCO World Heritage Site like North Korea in 2004. And after Korea registered Gangneung Danoje as a UNESCO Intangible Heritage of Humanity in 2005, China began to designate intangible heritage (Arirang, Ssireum, Nongak, Hanbok, Gayageum, etc.) related to ethnic Koreans in Manchuria as its national heritage.Regarding the calligraphy heritage, China was registered as a national heritage in 2008, and in 2009, the Chinese Calligraphy was registered as a UNESCO Intangible Heritage of Humanity. In response to China's move, Japan also launched the UNESCO Registration Promotion Committee in Japan in 2015 to register Japanese Seodo as a UNESCO Intangible Heritage of Humanity. However, in the case of Korean calligraphy heritage, it is coping in the opposite direction to this international situation. Korea rejected the designation of a nationally designated cultural property as a calligraphy heritage, and the calligraphy heritage infrastructure is indescribably poor compared to China and Japan. There is little awareness of this.In this situation, the government and the calligraphy community indicated the importance of the heritage and the justification for rehabilitation, and described the immediate challenges and action measures from the current standpoint. In addition, policy alternatives related to this were proposed.
