The dispute that occurred in the North Natuna Sea has attracted international attention, including the superpower United States of America and the People's Republic of China and countries in the Southeast Asian region. This escalation of tensions occurred when the People's Republic of China built military bases in areas considered the nine dash lines that the PRC claims as part of their country. International law continues to fail to enforce the North Natuna Sea. It is clear that international law has so far tried - and failed - to contain China's advances in the North Natuna Sea. Existing confidence-building measures must match China's increasingly hegemonic claims. If not, the rules-based order will face continued erosion and smaller countries in Southeast Asia will suffer the consequences. This study uses a qualitative approach with socio-historical analysis to reveal past events, especially in the field of maritime law, which are unknown to the international community.

AbstractWe examined and keyed out the subgenera of the genus Lepidocyrtus mostly created by Yoshii. Although many of these subgenera of the genus Lepidocyrtus are difficult to apply in Europe, America, and Africa, they are easily applicable in East and Southeast Asia. The species of Southeast Asia are placed in these subgenera and a key to the subgenera is provided. A new species, Lepidocyrtus (Lanocyrtus) felpei from Xinjiang, People's Republic of China, is described and the species Lepidocyrtus (Lanocyrtus) fimetarius Gisin is redescribed. Although the Lepidocyrtus fauna of the whole of East Asia differs from the Holarctic fauna, the Central and Northeast Asian fauna are similar in subgeneric make up to the North American fauna, slightly less similar to the European fauna, and totally unlike the Southeast Asian fauna.

The bilateral meeting between the United States and North Korea, whichwas held in Hanoi in February 2019, has not resulted in any agreementbetween the two parties. Furthermore, North Korea’s construction activityof a nuclear development facility in Tongchan-ri has threatened the possibilityof any agreement between both states and has shown North Korea’spoor commitment to denuclearization. In order to understand the attitudeshown by North Korea, it is important to consider the presence of anotherdominant actor in East Asia, the People’s Republic of China (PRC). Thisresearch aims to study the significance of the North Korean denuclearizationissue for the PRC, as well as the PRC’s position in the issue. This researchutilizes a document-based data-collecting method, which includesofficial documents released by the PRC as well as literatures that havecarried out earlier studies on the topic. This research has shown that thePRC possesses significant interests and power in the denuclearization ofNorth Korea, which require the country to maintain an unclear stance inthe denuclearization process of North Korea.

The Khalkha River (Khalkhin Gol), which forms part of the north-east frontier between the Mongolian People–s Republic (MPR) and the People's Republic of China (PRC), is famous in Mongolian history for the 1939 Battle of Khalkhin Gol (Nomonhan), in which joint Mongolian-Soviet forces finally repulsed the attempted invasion of the MPR by the Japanese Army of Manchukuo. Less well known, however, is the existence on the left bank of that river of one of Mongolia's most interesting religious antiquities, the remains of a gigantic Buddhist statue, known as the Great Buddha (Ikh Burkhan).

During the last 30 years, the human population of the Qaidam Basin in the People's Republic of China increased 27-fold. Much grassland was placed under cultivation, and vegetation on some sandy areas was nearly destroyed and remains in poor condition. Forests in the eastern region of the basin were degraded, and the total forest area was reduced. In addition, the number of domestic animals increased sharply, resulting in overloading of pastures; man-made disturbances, including hunting, increased enormously. For these reasons, the vegetative cover of the basin has been reduced, influencing the survival of wild animals. The senior author surveyed the basin during 1971, and the authors made a second survey in August and September of 1986. Several species of large mammals had apparently become extinct in the basin proper. Although the climate was more severe, there were more species of wild animals and their numbers were greater in the mountainous areas because of fewer disturbances. The authors offer views and suggestions on the protection and utilization of wild mammals of the basin.
