A China Coast Guard (CCG) vessel blocked a Bureau of Fisheries and Aquatic Resources (BFAR) ship on its way to BRP Sierra Madre in Ayungin (Second Thomas) Shoal in the West Philippine Sea in late June, according to Washington-based think tank Asia Maritime Transparency Initiative (Amti). The incident took place on June 27, or almost a week after the Chinese coast guard warned troops at BRP Sierra Madre of “consequences” if it makes “trouble,” which Philippine authorities construed to refer to the transport of construction and repair materials to the rusty and grounded warship.
