China expands Paracel artificial islands, extending military reach toward Vietnam

China is rapidly expanding two artificial islands in the disputed Paracel Islands, adding facilities that analysts say could extend Beijing's military reach toward Vietnam and key South China Sea shipping lanes. The expansion continues an established pattern of militarization in the Spratlys and Paracels, but the pace and proximity to Vietnam mark a notable escalation. The move raises regional tensions and could prompt responses from Vietnam and other claimants.
