币界网报道：Iran and world powers resumed nuclear talks in Oslo this week amid escalating tensions, as Tehran continues enriching uranium beyond limits set by the 2015 deal. The negotiations aim to revive the Joint Comprehensive Plan of Action (JCPOA), which the U.S. exited in 2018. European mediators expressed cautious optimism, while Iranian officials demanded guarantees against future U.S. withdrawals. Meanwhile, Israel reiterated opposition to any agreement allowing Iran to maintain nuclear infrastructure. The talks coincide with reports of Iranian cyberattacks targeting Western infrastructure, raising concerns about Tehran's negotiating sincerity. Market analysts warn prolonged deadlock could trigger oil price volatility.
