I found it strange to come across interference from a Chinese radio station on the BBC’s shortwave broadcast. For about a month, between April and May 2026, I was monitoring this special BBC radio service, transmitted from a station in Madagascar and aimed at Sudan and Gaza in Arabic. Aside from some technical and propagation issues, this was the first time I had encountered this kind of interference.

At first, I thought it was some sort of technical problem. The interference from the Chinese radio made it impossible to understand what was being said on the BBC broadcast. I tried again on other days, and the problem persisted. On May 25 at 17:00 UTC, I tuned into another BBC broadcast, this time transmitted from Ascension Island and aimed at West Africa in English, on the frequency 17780 kHz. To my surprise, the BBC broadcast was once again overpowered by the signal of a Chinese station — I couldn’t tell whether it was China National Radio or China Radio International (also known as CGTN Radio).

This monitoring was done on an Ecopower EP-F23B radio — a white-label model — with DSP technology and manual tuning. I wondered if it might be a problem with the device itself. So I used a digital Xhdata D808 radio, and when I tuned precisely to the frequency, I determined that the issue wasn’t a technical fault with my equipment, but rather deliberate interference with the BBC broadcast.

Faced with this situation, I started to believe this wasn’t a technical problem but an intentional act. I decided to investigate online, and it didn’t take long to find confirmation of my suspicions.

I found an article written in 2021 by two communication scholars, Yanqiu Zhang and Daniel Oloo Ong’ong’a, titled “Unveiling China’s digital diplomacy: A comparative analysis of CGTN Africa and BBC News Africa on Facebook.” It became clear to me that radio waves were once again the stage for geopolitical rivalry. The article focuses on the clash between the two broadcasters on social media, but clearly, this battle isn’t limited to the internet.

Continuing my research, I found news reports that illustrated this conflict well. On February 4, 2021, The Guardian reported: “Chinese state broadcaster loses UK licence after Ofcom ruling; Regulator concludes news network CGTN is ultimately controlled by Chinese Communist party.”

Well, well, ladies and gentlemen — we’re back to the good old days of the Cold War, aren’t we?

In contrast to the British broadcaster, Chinese CGTN has expanded its reach across the African continent, investing in digital platforms, but also in radio transmitters, programming in multiple languages, and the production of low-cost radios — with AM, FM, and shortwave, plus a flashlight and solar panel — taking into account that a large portion of Africa’s population has limited access to electricity and the internet.

A Chinese-made radio, with a solar panel, flashlight, AM, FM and shortwave bands, advertised by an electronics store in Nigeria for the equivalent of US$11.

Illustrated Radio Listening Report related to CGTN broadcast in Arabic. While the BBC announced in 2023 the end of its Arabic broadcasts, CGTN broadcasts in that language on 7 different frequencies daily.

The BBC’s soft power in Africa was built in the wake of Britain’s colonial past. CGTN, on the other hand, reflects the relationship China has consolidated with the African continent as its largest trading partner.

The BBC, like the United Kingdom, is no longer the empire it once was, struggling to maintain what little influence it has left with whatever budget remains. CGTN, however, is the portrait of a rising economic power — a China that builds its soft power the same way it built its economic leadership: with persistence and patience.

In January of this year, UK Prime Minister Keir Starmer visited the president of China Xi Jinping in an attempt to resolve differences between the two nations. Meanwhile, the shortwave battle between the CGTN and BBC continues. A clash between a declining power and an emerging one. This isn’t about chasing ratings. It’s geopolitics, played out on the radio waves, before the ears of the world.

In any case, these are conclusions I drew from the recent history of animosity between the United Kingdom and China, notably involving the BBC and CGTN. It’s possible the interference I detected is just technical problems, who knows? Perhaps a simple coincidence.
