Senegalese Prime Minister Ousmane Sonko recently expressed concerns about the erosion of international norms and the growing tendency of some powerful countries to unilaterally impose their own rules.
In an interview with China Media Group (CMG) released on Friday, Sonko, who was in China for the 2025 Summer Davos, criticized U.S. tariff hikes on its trade partners, emphasizing that certain nations have historically asserted their influence by establishing rules that primarily serve their own interests.
However, he noted that these countries now seek to break away from these rules because the world is now shifting towards a more balanced order.
"Increasingly, the concepts of international order, international rules, and the international community are losing their significance because we have certain countries, due to their power, that unilaterally assume power at every moment in history and set the rules for themselves. But it was these countries that created these rules because they felt powerful and thought that this would benefit them at the expense of the rest of the world. Today, things are tending to balance out. They want to break away from these rules or impose different rules," said Sonko.
He underscored the significance of initiatives from the Global South, particularly within the BRICS, a group of emerging economies, as vital steps toward fostering a more equitable, multilateral world.
"I think that today, what is being done in the Global South, and at the BRICS level, is quite important, and such work must continue for a much more balanced, multilateral world, and for a continent like Africa, we must take advantage of this situation," said Sonko.
The three-day 2025 Summer Davos Forum, held in north China's Tianjin Municipality in late June, attracted over 1,700 influential figures from more than 90 countries and regions to discuss how entrepreneurship and emerging technologies can unlock dynamic and resilient economies.

The Exhibition Hall of Evidence of Crimes Committed by Unit 731 of the Japanese Imperial Army in northeast China's Harbin released on Thursday a 38-minute video of a former member of Unit 731, a notorious Japanese germ-warfare unit during World War II (WWII).
In the footage, former Unit 731 member Tsuruo Nishijima detailed how the unit used meteorological data to carry out bacterial dispersal and frostbite experiments.
The video was recorded in 1997 by Japanese scholar Fuyuko Nishisato and donated to the exhibition hall in 2019, according to the hall, which was built on the former site of the headquarters of Unit 731 in Harbin, capital city of Heilongjiang Province.
Nishijima joined Unit 731 in October 1938 and served in the unit's meteorological squad. The squad was not a simple observation section but rather an auxiliary force supporting the unit's human experiments in the field by measuring wind direction, wind speed and other conditions to ensure optimal experimental results.
Nishijima confirmed in the footage that "the meteorological squad had to be present at every field experiment." He testified to the "rainfall experiments" conducted by Unit 731, which involved aircraft releasing bacterial agents at extremely low altitudes.
At a field-testing site in Anda City, Heilongjiang, Unit 731 aircraft descended to about 50 meters above the ground and sprayed bacterial culture liquids onto "maruta" -- human test subjects -- who were tied to wooden stakes. Each experiment involved about 30 people, spaced roughly 5 meters apart. After the experiments, the victims were loaded into sealed trucks and transported back to the unit, where their symptoms and disease progression were recorded over a period of several days.
Nishijima also revealed that a Japanese military doctor once died after removing the mask and becoming infected during an experiment, indirectly proving the extreme virulence of the bacterial agents.
The video further disclosed details of the meteorological squad's involvement in frostbite experiments. To study wartime needs in frigid regions, the invading Japanese army forced the victims to expose their bodies for five to ten minutes in temperatures ranging from minus 20 to minus 35 degrees Celsius and observed their physical reactions.
"For example, during frostbite experiments, we would be sent outside to observe the weather. They wouldn't bring many people out at once, only two or three, who would be forced to take off their upper garments or all their clothes. In fact, it was already quite tough to stay out there for five to ten minutes, because it was too cold," Nishijima said.
According to the exhibition hall, Unit 731 had a separate frostbite laboratory, with Hisato Yoshimura serving as the leader of the unit's frostbite study squad from 1938 to 1945.
In a paper on frostbite published in 1941, Yoshimura recorded data from live human experiments to study the occurrence of frostbite and pathological changes in the human body under different conditions.
"This is a form from the paper. Titled 'The Severity and Process of Frostbite,' it divides frostbite into three stages. The symptoms of the first-degree frostbite are redness and swelling. Blisters appear in the second stage. And the third-degree frostbite features necrosis and ulceration. It says here that, in the third stage, from the 50th to the 60th day, toes and fingers detached. There is no doubt that these data were obtained through numerous human experiments," said Tan Tian, a researcher of the exhibition hall.
Nishijima's video, a piece of oral history from a perpetrator's perspective, further reconstructs the criminal chain of Unit 731 and once again demonstrates that the invading Japanese army's biological warfare crime was systematic and inhumane, and was an undeniable historical truth, according to the exhibition hall.
"Unit 731's frostbite experiments were essentially conducted to prevent and treat frostbite during combat in cold environments. However, for the so-called prevention and treatment of frostbite, they caused frostbite on living people for experiments and data analysis. So in nature, it still serves the purpose of war," said Jin Shicheng, director of the Department of Publicity, Education and Exhibition at the hall.
Unit 731 was a top-secret biological and chemical warfare research base established in Harbin as the nerve center for Japanese biological warfare in China and Southeast Asia during WWII.
At least 3,000 people were used for human experiments by Unit 731, and more than 300,000 people in China were killed by Japan's biological weapons.
