Chinese authorities intercepts sixty thousand cartographic materials for 'incorrectly labeling' the island of Taiwan

Chinese customs officers in the coastal province of Shandong have confiscated sixty thousand maps that "incorrectly labeled" the self-ruled island of Taiwan, which Chinese authorities claims as part of its sovereign land.

The maps, authorities said, also "omitted important islands" in the South China Sea, where Beijing's claims overlap with those of its regional neighbors, including the Philippine government and Vietnam.

The "violating" maps, meant for export, cannot be sold because they "threaten national unity, sovereignty and territorial integrity" of China, officials confirmed.

Cartographic materials are a delicate subject for China and its regional competitors for reefs, islands and rock formations in the South China Sea.

Specific Compliance Issues

China Customs explained that the maps also omitted the nine-dash line, which demarcates Beijing's claim over almost the whole South China Sea.

The line comprises nine dashes which extends a significant distance southeastern direction from its most southerly province of Hainan.

The seized maps also did not mark the maritime boundary between China and the Japanese archipelago, authorities said.

Cross-Strait Situation

Authorities said the maps incorrectly labeled "Taiwan province", without specifying what exactly the incorrect labeling was.

China sees self-governed Taiwan as its sovereign land and has kept open the possibility of the use of military action to take the island. But Taiwanese authorities considers itself distinct from the Chinese mainland, with its own governing document and elected leadership.

Geopolitical Tensions

Tensions in the South China Sea periodically escalate - most recently over the weekend, when maritime craft from China and the Philippine government were involved in another encounter.

Philippine authorities alleged a China's maritime craft of purposefully hitting and using water cannons at a official Philippine ship.

But Chinese officials said the confrontation happened after the Philippine vessel disregarded multiple alerts and "moved perilously near" the China's maritime craft.

Previous Precedents

The Philippine government and Vietnam are also especially concerned to portrayals of the South China Sea in maps.

The popular motion picture from 2023 was prohibited in the Vietnamese market and modified in the Philippines for displaying a maritime chart with the nine-segment boundary.

The statement from China Customs did not specify where the confiscated materials were intended to be sold. China supplies much of the world's goods, from Christmas lights to stationery.

The seizure of "non-compliant cartographic materials" by Chinese customs officers is frequently occurring - though the number of the maps seized in the Shandong region significantly exceeds earlier interceptions. Merchandise that are non-compliant at the customs are destroyed.

In spring, customs officers at an air transportation hub in the coastal city confiscated a batch of 143 marine maps that featured "obvious errors" in the national borders.

In late summer, border authorities in the northern province seized two "non-compliant charts" that, among other things, contained a "improper representation" of the Tibet's boundaries.
