Beijing: A Chinese state-owned newspaper said on Monday that "war is inevitable" between China and the United States over the South China Sea unless Washington stops demanding Beijing halt the building of artificial islands in the disputed waterway.

The Global Times, an influential nationalist tabloid owned by the ruling Communist Party's official newspaper the People's Daily, said in an editorial that China was determined to finish its construction work, calling it the country's "most important bottom line".

The editorial comes amid rising tensions over China's land reclamation in the Spratly archipelago of the South China Sea. China last week said it was "strongly dissatisfied" after a US spy plane flew over areas near the reefs, with both sides accusing each other of stoking instability.
