Japan and South Korea took fresh swipes at one another Sunday, raising questions about whether relations between the U.S. allies would improve after they reached a last-minute deal Friday to rescue an expiring intelligence-sharing pact.

Late Sunday Japan rejected a South Korean complaint over the wording of an announcement that the two sides would hold talks on a dispute over export controls.

Japan's Ministry of Economy, Trade and Industry wrote on Twitter that the announcement had been in line with prior discussions with South Korea, after Seoul accused Tokyo of intentionally leaking and distorting information about the agreement.
