China withstood a late Korean surge to claim their second draw on the trot after they held Japan 3-3 on Sunday.
Korea, who kicked off their campaign with a goalless draw against Australia on Saturday, had several chances in the final 15 minutes but their forwards failed to convert any of them.
Yeom Kihun's curling free-kick from just outside the area breached China's defensive wall but was kept out by goalkeeper Zeng Cheng, who had pulled off a couple of spectacular saves in the first half.
Korea soon had another chance to score when Go Mooyul out-jumped his marker in the 82nd minute but headed over the bar.
Kim Shinwook's powerful header also missed the target after the forward got on the end of a cross inside the box just before the final whistle.
Japan meet Australia on Thursday in the next match in the tournament organised by the East Asian Football Federation.
