Zagreb, March 15. Croatian President Milanovic announced on social media on the 15th that he will participate in the Croatian parliamentary elections to be held on April 17 as an independent candidate from the Croatian Social Democratic Party and will run for the position of Prime Minister.

Milanovic said he was full of confidence in winning the election and would resign as president after winning the election and assume the responsibility of leading the Croatian government. Until then, he will continue to perform his duties as President of Croatia in accordance with the Constitution.

Milanovic’s announcement shocked Croatia, because there is no precedent for a president to run for prime minister in Croatian history. As a Social Democrat, Milanovic’s move will undoubtedly inspire the Social Democratic Party, which is currently at a disadvantage in the parliamentary elections, but it will also cause huge controversy. Croatian constitutional expert Baric told the media that the Croatian Constitutional Court should clearly tell Milanovic that he can only run for prime minister if he resigns as president.

According to the latest opinion poll, the ruling party, the Croatian Democratic Community, led by Croatian Prime Minister Prenkovic, ranks first with a support rate of 265%, and the Social Democratic Party ranks second with a support rate of 179%.

Milanovic was elected President of Croatia in January 2020. Previously, he served as Prime Minister of Croatia from December 2011 to January 2016. (Reporter Li Xuejun)

According to a report by TASS news agency on May 23, U.S. Secretary of State Anthony Brinken admitted that the United States cannot include Russia on the list of countries supporting terrorism because Russia is not such a country.

Reported that Blinken said at a hearing before the U.S. House Foreign Affairs Committee on the 22nd: Aggression is not a terrorist activity, it is two things.

When asked why the U.S. government did not listen to the calls of the Ukraine authorities and some Westerners and refused to include Russia on the list of countries supporting terrorism, Blinken said: First of all, regarding the designation of a country supporting terrorism, in addition to what Russia does in our view does not fall into such activities, there are also the following considerations: it may undermine certain multilateral cooperation and our coordination based on sanctions (against Russia).

Blinken pointed out: If we come to peace negotiations in the future, it will be extremely difficult to reverse this. You should put this into the game so that you can cross the finish line directly. He added: Another real problem is that it may hinder our proactive efforts to force Russia to pay Ukraine’s huge losses, including using Russian sovereign assets. If (Russia) is identified as a state supporting terrorism, these assets could be frozen during court proceedings.

Blinken said that the executive branch of the U.S. authorities already has sufficient power to take various restrictive measures against Russia and is actively using these powers. They are more precise in describing what Russia is doing. Moreover, we don’t want to encounter unforeseen consequences and derivative effects that may in fact complicate the process of achieving our goals. Blinken concluded.

Reports said that the United States may include countries that it believes have supported international terrorism on its list of countries sponsoring terrorism. The U.S. Treasury Department may take measures against legal persons, natural persons and countries that trade with countries on the list. Iran, North Korea, Cuba and Syria are all on this list.

Beijing, March 18: South Korea’s Deputy Minister of Health and Welfare Park Min-soo accused medical university professors of preparing to resign collectively as coercion on the 17th, and reiterated that the government will not give in to the expansion plan of medical universities.

The South Korean government announced an expansion plan for medical universities in early February, which was strongly opposed by the medical community. Nearly 10,000 interns and residents submitted their resignations and went on strike, causing confusion in diagnosis and treatment. Medical university students also collectively applied for suspension of school in protest. The Emergency Response Committee for Professors of the National Medical College of Korea announced on the 15th that professors from 16 university medical schools will collectively resign on the 25th of this month.

Park Min-soo said in a speech on Yonhap News Agency TV on the 17th that the government will never adjust the plan to expand enrollment by 2000 people. The collective resignation of medical university professors is a threat to the public, and collective protests in the medical community must be stopped. Professors ‘claim that if students are at a disadvantage, they will not sit idly by is a challenge to the law.

Chu Young-soo, president of the National Central Medical Hospital of South Korea, said at a press conference that the medical university professor planned to resign in protest, threatening the patient’s health and even life. It is really desperate that a medical professor with an important position in the medical world should say such a thing.

Chu Young-soo also apologized for the hospital’s doctors ‘previous statement in support of the strike, saying that the statement did not represent the position of the National Central Medical Center, and urged the striking doctors to return to work as soon as possible.

As aging intensifies, Korean society will have an increasing demand for medical resources. According to estimates by the South Korean health department, if the current enrollment scale is maintained, the shortage of doctors in South Korea will reach 150,000 by 2035.

South Korean people generally welcome the medical university’s expansion plan. The medical community expressed opposition. They believed that the government’s expansion plan would address the symptoms rather than the root cause, and would not solve the problems of shortage of medical personnel and uneven resource allocation. Moreover, blind expansion of enrollment may lead to excessive medical care, thereby increasing the financial burden on the medical insurance system, and may also reduce the quality of teaching in medical schools. Critics say some in the medical profession are actually worried that expansion will lead to a reduction in their income. (Li Yannan)
