China said it would host nuclear talks with Iran and Russia, days after US President Donald Trump urged Tehran to negotiate a new deal over its atomic work or face military action.

“The three parties will exchange views on the Iranian nuclear issue and other issues of mutual interest,” China’s Foreign Ministry said in a statement on Wednesday. The meeting will take place in Beijing on Friday and be attended by deputy foreign ministers from Moscow and Tehran, it said.

The summit comes amid a flurry of diplomatic activity on Iran’s expanding nuclear program. The International Atomic Energy Agency said last month that Tehran’s uranium enrichment has surged since Trump’s election victory in November. While Iran insists its nuclear program is for civilian purposes only, the West has longstanding concerns that the country wants to develop atomic weapons.

Last week, Trump said he had written a letter to Iran’s leadership, urging it to enter talks on a new agreement. The US President walked away from an earlier deal during his first term in 2018 and little progress has been made since then to revive the accord.

Iran has signaled it’s not ready for talks with the US. Supreme Leader Ayatollah Ali Khamenei says his country won’t be bullied into negotiations and that Trump’s decision to tear-up the original 2015 accord showed he cannot be trusted or taken seriously. Still, the country’s economic strains have led some senior officials to conclude that negotiations are needed to get sanctions eased.

Friday’s gathering in Beijing comes after two rounds of preliminary nuclear talks between Iranian and European diplomats in Geneva in recent months.

The fediverse promises social media without Big Tech – if it can avoid familiar pitfalls

You’ve probably noticed lately that a lot of people are trying out alternatives to the big social media networks X, Instagram and Facebook. For example, after Elon Musk bought Twitter in 2022 and started allowing far more disinformation and hateful content on the site, renamed X, advertisers and users started backing away. More recently, Meta’s decision to roll back hate speech rules has prompted many people to consider leaving Instagram and Facebook.

Some of the most popular new destinations include “federated” services like Mastodon and Pixelfed, as well as the quasi-federated Bluesky. Federated means decentralized – rather than one central service, like X, federated systems have tens of thousands of servers. They also tend to be nonprofit and community-run.

Federated services, otherwise known as “the fediverse,” have been hailed as a network for public communication, dialogue and debate, where ordinary people, not corporations, shape their social spaces, and where advertisers, hate speech and intrusive algorithms are much easier to avoid. News organizations, nonprofits, universities and even governments have experimented with the fediverse and Bluesky, partially or even completely shifting their social media presence away from X.

However, as we, researchers who study media and communications, and our coauthors Thomas Struett and Patricia Aufderheide describe in a recently published paper, history provides numerous examples of other promising platforms for the digital public sphere that have died untimely deaths. We identified potential pitfalls from these examples and ways to avoid them.

The fediverse in a nutshell.

We identified three such challenges: too many cooks, commercial capture and guilt by association.

Too many cooks

One nice thing about the big social media platforms is you know who’s in charge.

But instead of centralizing power like Meta or X, the fediverse has a distributed governance structure. While decentralized governance helps the fediverse avoid some of the pitfalls associated with the big social media platforms, like political censorship and surveillance capitalism, it introduces other risks that must be addressed before the fediverse can serve as a worthy replacement.

In short, when too many cooks are in charge, it’s hard to make a good meal. Take content moderation, for example. The fediverse offers great tools for blocking, and built-in codes of conduct, but these tools are specific to individual “instances” – the tens of thousands of fediverse servers. Who decides who gets blocked? With no central authority, governance is in the hands of fediverse members, who use hashtags like #fediblock to loosely coordinate. And that means people who are more likely to be harassed also end up having to do more of the work to prevent harassment.

Commercial capture

The fediverse, like email or the web itself, is open source. It was also developed with no input from the big social media platforms. But its origins won’t necessarily prevent the big platforms from taking over.

Look what happened to email, for instance. Once upon a time, there were thousands of different email providers. But today, nearly everyone is on Google’s Gmail and Microsoft’s Outlook, mostly because those companies added extra bells and whistles and sold email as a part of larger packages to employers, schools and other organizations.

This could easily happen again. Meta has already used fediverse protocols for its new microblogging service, Threads. While this helps Threads and Mastodon users to communicate, it also means Meta has a vested interest in shaping the technology’s future, in ways that might conflict with the hopes of today’s fediverse users — especially those who just fled Instagram and Facebook.

It’s easy to build your own social media platform in the fediverse. Running one is another matter.

Guilt by association

While some social media companies might seek to capture the fediverse, others might seek to undermine its reputation by highlighting some of its unsavory uses. This has happened with several beneficial alternative technologies in the past, such as peer-to-peer file sharing, the dark web and end-to-end encryption.

The fediverse is already facing such challenges. In 2023, researchers at Stanford University published a report suggesting that child sexual abuse material can easily find a home on the fediverse. Couple this with claims from researchers that “toxic content is prevalent and spreads rapidly” across the fediverse, and a terrifying narrative emerges in which child sexual abuse material is spreading out of control.

Though this content could flourish in pockets of the fediverse, the scary scenario of prevalent child sexual abuse material is not the case. There are many moderation tools, including shared blocklists, that prevent it. However, the idea that the fediverse is full of harmful content was used by Elon Musk to justify his anti-competitive decision to block links from X to Mastodon.

Can these platforms survive?

We’re still bullish on the fediverse, and on Bluesky, if it manages to become a truly federated platform.

But democratized tech doesn’t guarantee democratic outcomes.

If these platforms are going to deliver on their promise, it’s important to learn from the mistakes of the past. That will mean users putting in the work to make sure they remain safe, accessible, noncommercial and well respected.
