消息人士：美国展现有限灵活性但不会在核要求和海峡问题上让步

Odaily Planet Daily News: Sources say Pakistan's Interior Minister is in Tehran for a new round of talks. It is understood that the U.S. has intensified demands regarding Iran's nuclear program and the security of the Strait of Hormuz, while indicating that it will not soften its stance on these two core issues. Sources say Washington has shown only limited flexibility in easing sanctions, while Iran remains unconvinced by U.S. assurances about avoiding renewed conflict. (Jinshi)
