Vietnam has reportedly halted a gas-drilling expedition in a disputed area of the South China Sea following threats from China. The company behind the drilling, Repsol of Spain, was ordered to leave the area, according to a source in the Southeast Asian oil industry.
It comes only days after it had confirmed the existence of a major gas field. Those reports have been corroborated by a Vietnamese diplomatic source.
According to the industry source, Repsol executives were told last week by the government in Hanoi that China had threatened to attack Vietnamese bases in the Spratly Islands if the drilling did not stop.
China claims almost all of the South China Sea, including reefs and islands also contested by other nations.
The drilling expedition began last month in an area of sea about 400km (250 miles) off Vietnam’s southeast coast.
Talisman-Vietnam was formerly owned by the Canadian company Talisman, but since 2015 has been part of the Spanish-owned Repsol group.
One analyst, who did not want to be named, estimated that Repsol has spent about US$300million on developing the field so far.
It has therefore come as a surprise to observers that Vietnam should have backed down so quickly.
In 2014, coastguard vessels and other ships belonging to China and Vietnam confronted each other in a different area of the South China Sea, further north, near the Paracel Islands. Since then the two countries have tried to avoid confrontation.
