A Chinese research vessel, the Dayang Yihao, has been operating in the Arabian Sea since December 19, according to maritime analysis group SeaLight. The vessel, equipped with advanced ocean floor imaging systems, has been surveying the area west of India. Independent military observers suggest the Dayang Yihao may have been operating near the USS Abraham Lincoln aircraft carrier, though the exact distance is unknown. The US has increased its naval presence in the region, citing concerns about Iran's nuclear program, crackdown on protestors, and alleged threats to regional stability. The presence of both the US aircraft carrier and the Chinese research vessel in the same area highlights the heightened military activity in Middle Eastern waters.
