According to a report by Yonhap News Agency on March 20, the South Korean government officially announced on the 20th the results of the allocation of 2000 places to expand the enrollment of 2000 students in the national medical school year. As a result, the medical school enrollment expansion plan has been settled in 27 years. In order to expand local medical infrastructure, the government will allocate 82% of the new places to non-capital area colleges and universities, and the remaining 18% will be allocated to Gyeonggi Province and Incheon areas. The number of schools in Seoul will remain unchanged.

Minister of Education Lee Zhouhao announced the results of the allocation of enrollment places for medical schools in the 2025 academic year, including the above contents, at the Central Government’s Seoul Office Building on the same day. The Ministry of Education received applications for medical school enrollment quotas from 40 universities across the country from February 22 to March 4. After that, it discussed with experts through the Expansion Allocation Committee and released the results.

The results show that the 27 university medical schools in non-capital areas will expand enrollment by 1639 students, accounting for 82% of the total enrollment expansion. At present, the number of students enrolled in non-capital medical schools is 2023, accounting for 662% of the national medical school enrollment scale (3058 students), and will increase to 3662 starting next year, accounting for 724% of the total enrollment scale.

In the Capital Region, the government has allocated 361 expanded enrollment places to five universities in Gyeonggi Province and Incheon City with enrollment sizes of less than 50 students, but the eight universities in Seoul have zero new places.

The Ministry of Education explained that the allocation of quotas is mainly considered to alleviate the imbalance between medical resources in the capital and non-capital areas, so that citizens can enjoy high-quality medical services in any region. The allocation committee comprehensively considered the materials submitted by each institution, educational conditions and future plans, and contribution to regions and essential medical care.

This is the government’s expansion of the enrollment scale of medical schools in 27 years. Analysts believe that although the medical profession still strongly resists the enrollment expansion policy through collective resignations, the government announced the allocation results on the same day, and the enrollment of medical students has been settled. The Ministry of Education plans to work with relevant departments to improve medical education conditions and provide support for institutions to hire professors and expand facilities.

United Nations, May 21: Fu Cong, Permanent Representative of China to the United Nations, delivered a speech at the Security Council open debate on the protection of civilians in armed conflict on the 21st, emphasizing that the elimination of armed conflict is the greatest protection for civilians.

Fu Cong said that saving lives in armed conflicts is certainly a noble goal, but it must be noted that as long as the conflict does not subside, civilian lives will be threatened at any time. At the same time, we must not forget that the primary responsibility of the Security Council is to maintain international peace and security. The Gaza conflict, which has lasted for more than seven months, has caused unprecedented civilian casualties and humanitarian disasters, and the lives of the millions of people currently gathering for refuge in Rafah are at risk. The Security Council should make promoting an immediate and comprehensive ceasefire a top priority. To this end, further action should be taken to urge Israel to immediately stop collective punishment of the Palestinian people and stop advancing its military offensive against Rafah, so as to give the people hope for survival.

Fu Cong said that international humanitarian law is the bottom line that must be jointly observed. The Security Council should continue to safeguard the authority of international humanitarian law and ensure its universal and uniform application. Double standards and selective application of humanitarian law are unacceptable and are tantamount to condoning more illegal activities in disguise.

Fu Cong said that attention should be paid to responding to the outstanding challenges brought by the proliferation of small arms and light weapons and the development of autonomous weapon systems. China calls for strengthening global governance of the arms trade, combating the illegal transfer of small arms and light weapons, and calls on all countries not to provide weapons to non-state entities. The risks of artificial intelligence and autonomous weapon systems as means of warfare are rising and deserve great attention. Countries should adhere to the principles of putting people first and intelligence for good to ensure that artificial intelligence is always under human control. China supports the formulation of a legally binding international instrument around lethal autonomous weapon systems.

Fu Cong said that improving the governance capabilities of countries involved in conflicts is the fundamental solution. When dealing with conflict situations, the international community should take systematic measures to support countries parties to conflicts in effectively enhancing their national defense, public security and counter-terrorism capabilities. At the same time, it is necessary to help the countries concerned accelerate development and gradually resolve the deep-seated causes of conflicts. China is willing to continue to work with the international community to make unremitting efforts to eliminate the scourge of war as soon as possible and ensure the happiness and tranquility of the people.
