New research confirms that China is operating oil and gas vessels and fixed structures within Taiwan’s exclusive economic zone (EEZ). This activity, which was documented in July and August, is being described as a “greyzone” approach—a strategy to push boundaries without triggering open military conflict. At least a dozen assets were observed, including massive wellhead platforms, with one vessel reportedly venturing within 50km of the restricted waters near the Pratas Islands.
Experts argue that these operations are designed to blur the distinction between legitimate commercial activity and strategic coercion. By consistently operating within these contested waters, China aims to normalize its presence and gradually reduce the area that Taipei can effectively patrol and defend. This incremental strategy is a key part of China’s long-term plan to assert its control over the South China Sea.
Taiwan’s official response has been notably quiet, which has concerned some observers. Critics warn that a muted reaction risks normalizing the encroachment. The lack of a stronger pushback is attributed to a combination of legal and capacity constraints that make a forceful response difficult to mount. Taiwan is in a precarious position, as it must balance the need to assert its sovereignty with the risk of escalating the situation.
The presence of fixed structures like wellhead platforms indicates a long-term commitment to these operations. This is not a temporary presence but a more permanent one, designed to solidify China’s claims in the region. The establishment of these platforms is a clear signal of Beijing’s intent to control the resources in the area, regardless of Taiwan’s sovereignty.
The situation serves as a stark reminder of the challenges posed by “greyzone” tactics. These actions, which fall below the threshold of armed conflict, are difficult to counter using traditional military or diplomatic means. They pose a significant threat to regional stability and international maritime norms. The international community is still grappling with how to effectively respond to these types of incursions.
