Asian stocks open lower as Brent crude trades above $78 a barrel

The U.S. issued a 60-day license allowing Iran to sell oil on the international market, offering Tehran an economic buffer as nuclear talks show partial progress but public differences remain over inspection terms. Brent crude edged up to trade above $78 a barrel. MSCI’s Asia regional share gauge slipped 0.2% in early trading, with South Korea’s Kospi down 1.3% and Japan’s Nikkei 225 off 0.3%. S&P 500 futures also moved lower amid a cautious risk backdrop.
