What are the key global events shaping international relations in January 2025?

Several January 2025 developments shifted diplomatic priorities, from a new U.S. administration to fragile ceasefires and sharper regional conflicts. These were among the month’s most consequential:

• Donald Trump returned to the White House. On January 20, he ordered the United States to begin withdrawing from the Paris Agreement and the World Health Organization. The orders began withdrawal processes; neither meant the U.S. had left immediately. His comments about tariffs on Canada and Mexico, NATO spending, Greenland, and the Panama Canal also unsettled allies and raised questions about the direction of U.S. foreign policy.
• A Gaza ceasefire began. A truce between Israel and Hamas took effect on January 19 after mediation by Qatar, Egypt, and the United States. Its first phase included hostage and prisoner releases and expanded humanitarian aid. The deal offered a pause in fighting, but the next stages—and a lasting settlement—remained uncertain.
• The war in eastern Democratic Republic of the Congo escalated. M23 fighters entered Goma on January 27, intensifying a crisis with regional implications. The Congolese government accused Rwanda of backing the group; Rwanda denied supporting M23. The fighting heightened fears of a wider confrontation between the two countries.
• Indonesia joined BRICS as a full member. The move, announced on January 6, added Southeast Asia’s largest economy to the group and reflected efforts by emerging economies to gain more influence in global institutions.
• Syria’s post-Assad transition remained a diplomatic test. Governments and international organizations weighed how to engage with the new authorities and whether sanctions could be eased, while seeking assurances about an inclusive political process and the protection of minority communities.

Meanwhile, Russia’s war against Ukraine continued to shape European security, and Sudan’s conflict remained a major humanitarian and diplomatic crisis. Taken together, January’s events showed how quickly alliances, regional stability, and international institutions could become central to foreign-policy debate.
