HONG KONG/MANILA, April 15 (Reuters) - China is employing ships and a barrier to tighten control of the entrance to the Scarborough Shoal in the South China Sea amid roiling tension with the Philippines over the disputed feature, satellite imagery obtained by Reuters shows.
Scarborough is one of Asia's most hotly disputed maritime sites, where some diplomats and analysts fear long-running frictions and confrontations could degenerate into armed conflict.
The presence of four fishing boats, a Chinese naval or coast guard ship and a new floating barrier comes as the Philippines sends its own coast guard and fisheries vessels to support its fishermen frequently driven away by larger Chinese patrols.
Photographs taken on April 10 and 11 show the fishing boats anchored along the entrance to the shoal, in addition to a floating barrier stretching across it in the April 11 image.
Satellite image provider Vantor, formerly Maxar Technologies, said a probable Chinese naval or coast guard patrol vessel can be glimpsed just outside the entrance on April 10.
China's defence ministry did not immediately respond to Reuters' requests for comment on the deployment to the entrance to the shoal or its timing.
TRADITIONALLY RICH FISHING GROUND
The traditionally rich fishing ground of the Scarborough Shoal lies entirely within the Philippines' exclusive economic zone, but China also claims it as part of its territory.
Last year, China approved establishment of a national nature reserve there, alarming Philippine security officials, who called the move a "clear pretext for occupation".
Jay Tarriela, a spokesperson for the Philippine coast guard, told Reuters on Wednesday the Chinese government had installed a 352-m (1,150-ft)floating barrier at the entrance on April 10 and April 11.
"Six Chinese maritime militia vessels were observed within the shoal, while three others were spotted outside, seemingly obstructing the entrance to BDM," he said.
He was referring to the shoal by its Philippine name of Bajo de Masinloc, while China calls it Huangyan Island.
While the Philippines coast guard has cut barriers in the past, Tarriela said the Chinese side appear to have removed the latest one since the weekend, but the Philippine Navy says its patrols continue.
"According to our assessment in the past, they consistently exhibit suspicion whenever they monitor a group of Filipino fishing boats," Tarriela added.
Ten Chinese coast guard vessels were sighted at the shoal from April 5 to April 12, Philippine Navy spokesperson Roy Trinidad said on Tuesday.
SOVEREIGNTY HAS NEVER BEEN ESTABLISHED
Despite the competing claims, sovereignty has never been established and the shoal is effectively under Beijing's control even if Philippine boats still try to operate there.
In January, the militaries of the Philippines and the United States sailed together at the shoal in the 11th such drill by the treaty allies.
Military engagements between them have soared under Philippine President Ferdinand Marcos Jr., who has pivoted closer to Washington in response to China's growing presence in the busy waterway of the South China Sea.
Thousands of troops from both countries are set to begin large-scale exercises across the Philippine archipelago this month, including in Zambales, whose coast is about 120 nautical miles from the Scarborough Shoal.
Diplomats say the drills and broader tensions are being closely watched amid fears that China could take advantage of perceptions that the U.S. is distracted by the Iran conflict and its effort to re-open the vital Straits of Hormuz waterway.
China has kept a deployment of coast guard and fishing trawlers at the shoal since seizing it in 2012 after a standoff with the Philippines.
Manila has said Chinese maritime militia operate some trawlers at the shoal and other disputed areas of the South China Sea, but Beijing has never acknowledged this.
A landmark 2016 ruling on various South China Sea issues by the Permanent Court of Arbitration backed Manila, but establishing sovereignty over Scarborough Shoal was outside its scope.
The court said Beijing's blockade there violated international law as it was a traditional fishing ground for several countries, including China, the Philippines and Vietnam.

China deployed ships and a floating barrier to block the Scarborough Shoal's entrance, increasing control over the area.
Scarborough Shoal is a traditionally rich fishing ground and a highly disputed maritime site between China and the Philippines.
The Philippines has sent coast guard and fisheries vessels to support its fishermen and contest Chinese control around the shoal.
No, sovereignty over Scarborough Shoal has never been established despite competing claims by China and the Philippines.
Military exercises between the Philippines and United States near the shoal have increased in response to China's growing presence.
