Export controls are a standard international practice. They involve prohibitive or restrictive measures on the export of dual-use items， military products， nuclear materials， and other goods， technologies and services related to safeguarding national security and national interests， and other restrictions related to fulfilling non-proliferation and other international obligations.The world is undergoing profound changes of a scale unseen in a century， with an increase in destabilizing factors and uncertainties， disruption to international security and order， and challenges and threats to world peace. The status and role of fair， reasonable， and non-discriminatory export control measures is growing in importance as an effective means to address international and regional security risks and challenges and safeguard world peace and development. All countries pay close attention to export controls and take an active approach to strengthening and standardizing their approach by establishing and enforcing measures through their legal systems.

The 20th century was a time of incredible change in China.My generation felt lucky and blessed to be born in the 20th century， survive its vicissitudes， and witness the transformation of the country. Poverty-stricken in our youth， we were fortunate to become workers， fighters， and crafters of the development of science and technology in China， and be granted the opportunity to share in making the changes happen. Most of my contemporaries saw the success and failure， windstorms and tempests， suffering and tears， and ultimately the rejoicing and jubilation that we experienced， as being all part of life in the great era. That experience should be preserved for generations to come， and for historians interested in Chinese studies.

Under British colonial rule， there was no democracy in Hong Kong. After resuming the exercise of sovereignty， the Chinese government implemented the basic policy of One Country， Two Systems and established democracy in the Hong Kong Special Administrative Region（HKSAR）. It has since provided constant support to the region in developing its democratic system. The determination， sincerity， and efforts of the Communist Party of China（CPC）and the Chinese government to this end have remained consistent and are obvious to any objective observer.Hong Kong has faced an extended period of damaging social unrest caused by anti-China agitators both inside and outside the region. Over the years， those who attempt to overturn the new constitutional order and destabilize Hong Kong and the rest of China have colluded to obstruct the democratic process. On the pretext of "fighting for democracy"， they have attempted to stage a color revolution， split Hong Kong from China， and seize power there. Their attempts have gravely threatened the order established by the Constitution of the People's Republic of China（Constitution） and the Basic Law of the Hong Kong Special Administrative Region（Basic Law）， thus endangering China's national security and Hong Kong's stability and prosperity.

爱国主义教育理论的建构视角对其能否直接指导或应用于爱国主义教育实践具有重要的决定作用。本书运用马克思实践论思维方式，针对教育对象、教育内容、教育策略与方式等主要教育活动要素展开着眼于实践的理论探索，促使理论建构立足“现实的人”，即教育对象，以及其他教育活动要素立足“现实生活世界”，即向具体化维度延伸。以此建构的爱国主义教育理论的整体性、针对性和实践性更加突出，能够为爱国主义教育的具体实践提供参考。

Rich in data and vividly written， this book depicts the complex and ever-changing geography and unique socio-cultural environment of the regions along the Polar Silk Road （PSR）. It also elaborates on the current status and development outlook of the PSR. Within the context of global climate change， this book proposes a strategy for China and other parties to jointly build the PSR. For those who seek to understand China， this brilliantly written book decodes China's relationship with the Arctic and is a timely release keeping abreast of the development needs of our time.As a supplement to the BRI， the PSR is conducive to building a "community with a shared future for mankind." Moreover， it cames forward and advances the purposes of the Charter of the United Nations. As a near-Arctic state and an observer of the Arctic Council， China has the responsibility and obligation to participate in Arctic governance， and is expected to play its role as a responsible power. In the face of environmental changes in the Arctic， China's initiative to jointly build the PSR is an affirmation of the Chinese people's commitment to serving all mankind.
