With inter?Korean high?ranking officials having a successful contact in August 2015, South Korea and North Korea begins their new relationship and Park Geun?hye government’s “trust building process” also makes progress. Political initiatives towards unification such as Park’s “Eurasia Initiative” is also expected to be invigorated. Together with a sincere inter?Korean reconciliation and cooperation will develop China and North Korea’s relation and economic cooperation, which will also give positive effect to sound development of inter? Korean relation, and eventually facilitate favorable conditions for North Korea to take reform and development. The reform and opening up experience of China indicate that highly centralized planning economy system does not suit to socialism, thus should be abandoned without any hesitation. Whether a market economy can be established in North Korea rests on the self?innovation of its economic policy. However, in China? North Korea’s economic cooperation, applying to market economic ethics will further promote North Korea’s reforming momentum. It is wrong to set the goal of economic cooperation as conducting North Korea’s reform at the very beginning. The new development strategy which focuses on economic construction and the underlying determination to reform are the source of impetus for North Korea’s reform and development. What should be done in the first place is to establish common interests and strengthen the power of economic cooperation. North Korea can learn successful experience of Chinese enterprises through China?North Korea’s  economic cooperation, combining development with support, wealth with rewarding, economic benefit with social benefit, which will form common interests between the two parties. According to this, North Korea’s modern agricultural economy through agricultural cooperation with North Korea, build foundations for North Korea’s economic development through supporting in infrastructure, promote international cooperation through supporting in establishing North Korean Economic Development Zone and involve North Korea in
international cooperation through implementation of “One Belt One
Road” strategy are needed. Entering the era of Kim Jong Un’s ruling, North Korea’s core key word is ‘Change’.
First Chairman Kim Jong Un’s new political ideas which is “Peoplecentered, National Prosperity led by science and technology” resolves the problem of how to adhere to the KIM Il Sung ? KIM Jong Il Doctrine in new situation and new environment and it will have a deep impact to liberation of the North Korean people’s thoughts. After first chairman Kim Jong Un takes power, new economic development measures were established. It is difficult to interpret North Korea's current new economic development measures as reform and opening?up. It is better to consider it as the strategy of re?promoting modernization in a new period. In other words, from institutional perspective, it is a socialist system, from the perspective of development path, it is industrialization strategy, from the perspective of development method, it is limited opening, and from the perspective of development model, it is government?led.
The third generation?Kim Jong Un’s mission is to develop and resolve people’s livelihood issue. Besides, Kim Jong?un’s regime has already entered a crucial phase, where he needs to keep stabilizing domestic situation as well as pay more attention to foreign relationship management. Despite of the limited impacts of international economic cooperation, North Korea’s basic path to development is still likely to be that the opening?up through international economic cooperation stipulates domestic reform, and such reform propels further openingup. Harmonious external environment would become indispensable for North Korea to achieve further development. While under the current circumstances of sanction and confrontation, it is rather difficult to make material progress. In this sense, facilitating external environment can be deemed as necessary condition for North Korea to increase reforming efforts. The most important part in improving North Korea’s foreign relations is improving inter?Korean relations. There is thus no other choice but to expect the role of South Korea in the process of facilitating North Korea’s external environment for reform and development, and President Park Geun?hye’s import role in improving trust within Korea Peninsula is further highlighted. If South Korea is able to wisely fulfill such role, with North Korean nuclear issue’s being resolved, a new era of Eurasia and Northeast Asian cooperation will come and the reunification is possible to be realized.
