Missing from the left
Only 3 of the 12 outlets with a published leaning rating that ran this story are rated left.
A reader who follows the left would not have seen this. We report the absence rather than explain it: outlets choose what to cover for many reasons, and we have no evidence about which one applies here.
China has completed the first phase of construction on Antelope Reef in the Paracel Islands, a disputed area of the South China Sea. Satellite images reviewed by Reuters show the outline of a 6 km artificial island with a straight shoreline exceeding 3 km. The images also reveal a 680-meter pier and the early stages of a helicopter landing area.
Barges and dredgers left the site after at least six months of work, as reported by Yonhap News Agency. Analysts cited by multiple outlets say the island will form part of China’s largest military base in the region. The base is expected to enhance Beijing’s surveillance and defence capabilities, particularly in the event of a conflict over Taiwan.
China has not publicly acknowledged building a military base on Antelope Reef. Yonhap News Agency reported that Beijing has previously described similar facilities as civilian, including for weather forecasting and scientific research. Vietnam also claims sovereignty over the Paracel Islands, which China has controlled since 1974.
What the coverage left out
No left-rated outlet ran the story. None of the digests from centre-rated outlets mentioned the specific strategic analyses published by Yonhap News Agency, including the island’s potential role in nuclear submarine defence or its impact on US and Vietnamese submarine operations. The centre-rated digests also omitted the names of the analysts quoted by Yonhap.

How each side covered it
Our own reading of the reporting listed below, written from the outlets’ articles rather than quoted from them. The reasoning is set out on our methodology page.
Left
3 rated outlets
- The three left-rated outlets all reported that China has finished the first phase of construction on Antelope Reef in the Paracel Islands. They agreed the site is an artificial island built in the South China Sea, with satellite images showing new structures.
- Sözcü and the Taipei Times led on the military purpose of the base. Sözcü described a 6-kilometre-long island with a harbour and helipad, suggesting it could be used in a Taiwan conflict. The Taipei Times called it part of China’s largest military base in the region. IBTimes Singapore did not specify the base’s intended use.
- None of the digests mentioned China’s stated civilian justification for the project. Sözcü alone noted Beijing’s claim that the construction is for civilian and scientific purposes.

5 rated outlets
- The four centre-rated digests led on the completion of the first phase of construction and the military significance of the island. Reuters, The Japan Times, Asia One, and WTVB all reported that analysts expect the island to form part of China’s largest military base in the South China Sea. The digests included the length of the island, the presence of a pier, and the potential for a runway.
- None of the centre-rated digests mentioned the specific strategic analyses quoted by Yonhap News Agency, including the island’s potential role in defending China’s nuclear submarines or complicating US and Vietnamese submarine operations. The digests also did not include the names of the analysts cited by Yonhap.
Right
4 rated outlets
- The two right-rated reports, Yonhap News Agency and Free Malaysia Today, led on the military implications of the island. Yonhap’s full report described the island as a potential "core stronghold" in a future Taiwan conflict and quoted analysts who said it could serve as a "fortress" for China’s nuclear submarines.
- Yonhap used the phrase "military megabase" to describe the facility and quoted Ben Lewis, founder of PLA Tracker, who said Antelope Reef could become "one of the most defensible key points" in China’s military network. Free Malaysia Today’s digest summarised the island’s role in strengthening Beijing’s "military hold and surveillance capabilities" but did not include specific strategic analyses.
Questions about this coverage
- How did the left and right cover China completes first phase of military base on Antelope Reef in…?
- Of the 12 outlets on this story carrying a published leaning rating, 25% are rated left, 42% are rated centre, 33% are rated right. Those percentages are shares of the rated outlets, not of every outlet that ran it, which was 19. The sections above set out what each side emphasised, in its own terms.
- Is China completes first phase of military base on Antelope Reef in… left or right?
- Neither side dominates it. Of the 12 rated outlets on this story, 25% are rated left, 42% are rated centre, 33% are rated right, and no side holds the 70% this site would want before calling a field one-sided. A story is not left or right in any case; the outlets that carried it are what carry ratings.
- Is the coverage of China completes first phase of military base on Antelope Reef in… biased?
- China completes first phase of military base on Antelope Reef in Paracel Islands is one event reported by 19 outlets, and this page does not rate the story as biased or unbiased. What it publishes is the spread: which outlets ran it, where named rating organisations place each of them on the spectrum, and what each side chose to lead with. A leaning rating describes an outlet's record over time, not this article, and the two should not be run together.
- Which side is not reporting China completes first phase of military base on Antelope Reef in…?
- When we first saw this story, outlets rated left had barely covered it. Coverage accretes for hours after an event, so that is where to look rather than a verdict — the split above is the current count, and it is the one to read.
- Which outlets covered China completes first phase of military base on Antelope Reef in…?
- 19 that we know of, every one of them listed further up this page with a link to its own report and to what we hold on the publisher. Nothing here is a summary of somebody else's summary: the outlets are named so the original reporting can be read.
