SEOUL, South Korea — South Korea appeared to ease its stance on North Korea on Thursday by calling for dialogue to help defuse tensions, as its president moved to calm foreign investors whose confidence the North has tried to shake with increasingly belligerent maneuvers.

“We hope the North Korean authorities come out to the dialogue table,” Unification Minister Ryoo Kihl-jae, South Korea’s point man on the North, said in a nationally televised statement that deplored the North’s recent decision to suspend the operation of an industrial park the two Koreas have run together for eight years in the North Korean town of Kaesong. “We strongly urge North Korea not to stoke the crisis on the Korean Peninsula any further.”

Mr. Ryoo stopped short of calling his statement an official proposal for dialogue. But it was a considerable softening in tone by President Park Geun-hye's government.

Until now, South Korea has categorically rejected any early dialogue with the North, believing that doing so amid a torrent of North Korean threats to attack the South would amount to capitulation and would only embolden the North’s brinkmanship. On Monday, Mr. Ryoo said the South had no intention of talking with North Korea anytime soon because it was unlikely to bring about "concrete results." On Tuesday, Ms. Park vowed to end a "vicious cycle" of South Korea's answering North Korea's hostilities with compromise.
