TOKYO - Asian stocks turned lower on Thursday as investors fretted about the simmering tensions between the United States and North Korea, sending Seoul shares skidding to two-month lows even as the previous day's rush into safe-haven assets appeared to slow.

"Some investors had wanted reasons to unwind their long positions built up in emerging market equities, and they found an opportunity in the latest bout of Korean tensions," said Kota Hirayama, senior emerging markets economist at SMBC Nikko Securities in Tokyo.
"At the moment, it is unclear how the Korean situation will play out and that is hampering the markets. But as past incidents involving the Korean Peninsula have shown, the impact on financial markets tends to fade away over a span of few days."
The declines in some Asian bourses, like Japan's Nikkei, were limited after Wall Street shares closed barely lower overnight, trimming losses, as investors appeared to brush off geopolitical concerns.

Furthermore, the benchmark Treasury yield also climbed away from lows," said Junichi Ishikawa, senior forex strategist at IG Securities in Tokyo.
"These developments suggest that risk aversion caused by geopolitical tensions in North Asia are temporary in nature, as long as it does not involve military conflict."
