(ATTN: UPDATES throughout; CHANGES photo) SEOUL, May 15 (Yonhap) -- South Korean stocks turned higher to breach the landmark 8,000-point level Friday, after opening marginally lower, tracking overnight gains on Wall Street boosted by a rally of artificial intelligence (AI)-relates shares and a positive evaluation of the U.S.-China summit.
