For civilians and former soldiers in liberated parts of Ukraine, the memory of six months of Russian occupation is fresh as they seek to reclaim their dignity. Accounts of abuse are still emerging.

In Toronto, where lack of affordable housing is reaching critical levels, activists are trying to reframe housing development in terms of community and empathy, rather than competition for resources.

Will minority communities most affected by criminalization and incarceration now be locked out of what is becoming a legal multibillion-dollar industry? What states and the federal government are doing to help restore the inequities of the past.

In India, a newspaper by and about street children offers a rare look into a community often described as “invisible.” Its success shows change is possible when vulnerable groups have the opportunity to tell their own stories.

From the moment of Russia’s invasion of Ukraine, observers have worried that it would do lasting harm to international rules meant to preserve the sovereignty of nations, restrain the use of force, and protect innocent life. One place where those rules may now be finding renewal is Ethiopia.

After two years of civil war, representatives of Ethiopia’s federal government and leaders of a rebellious state have gathered to talk peace. The negotiations, which opened today in South Africa and are set to run into the weekend, are fragile. They follow two months of intensified fighting. There is little more on the agenda beyond the hope of setting an agenda.

The urgent topic is how to end a humanitarian crisis that threatens wider regional instability. The conflict has cost half a million lives, displaced millions, and left the state of Tigray – home to 7 million people – on the brink of mass starvation. The United Nations has accused both sides of war crimes.

The humanitarian toll points to deeper stakes in the talks. As the largest and most powerful country in the Horn of Africa, Ethiopia lies in the middle of great power competition in both Africa and around the Red Sea. The contest for influence isn’t just about national or commercial interests. International norms must be reaffirmed, too.

Russia and China view Ethiopia’s war as an internal matter and have sought new investment ties despite humanitarian concerns. That no-strings-attached approach has left Western countries wrestling to stay in the game without surrendering their values. In July, for example, the European Commission approved $80 million for education and health projects, but stipulated that it must be dispersed “outside of government structures.”

“There’s an openness to engage based on progress, and real concerns about China and Russia filling any gaps,” one European diplomat told Politico. “But at the same time, we can’t just throw out our norms and values.”

The talks in South Africa reflect that same approach. They follow months of diplomacy by the African Union, the United Nations, the United States, and Europe. The key to any progress is their demand for an immediate cease-fire and unfettered access to Tigray for relief efforts. Beyond that, they seek cooperation from all sides in finding accountability for atrocities committed during the war.

That insistence on respect for humanitarian norms has already had an effect. Both sides acknowledge the war cannot be won militarily. And last week, the government stated that it “deeply regrets any harm that might have been inflicted upon civilians ... and will investigate such incidents to establish facts and provide redress when and if such unintended harm occurs.”

Admissions like those matter, even if they may not be fully sincere. “States have always sought to interpret legal norms to support their courses of action,” noted two legal scholars at the Liverpool John Moores University, in a recent article in the Netherlands International Law Review. “This in itself highlights the value which is attached to the system of international law and the perceived legitimacy which derives from its invocation.”

At a time of shifting competition between great powers and emerging middleweights, wars anywhere send ripples everywhere. The war in Ethiopia has devastated a fragile region. Now its parties, and the international partners bringing them to the negotiating table, are showing that strategic and humanitarian interests are not incompatible.
