Former U.S. National Security Adviser H.R. McMaster has questioned Pakistan’s role in efforts linked to Iran talks, saying the country appears too closely aligned with China to be seen as a neutral player. His remarks have added fresh scrutiny to Islamabad’s diplomatic outreach at a sensitive time in West Asia.

McMaster’s comments came as Pakistan continues to present itself as a possible bridge in regional diplomacy, including conversations involving Iran. But his criticism suggests that some U.S. observers view Pakistan’s involvement less as neutral mediation and more as a move shaped by strategic dependence on Beijing.

The former NSA’s use of the phrase “China’s client” reflects long-standing concerns in Washington about Pakistan’s deep political, economic and military ties with China. That relationship has become a major factor in how Pakistan’s foreign policy is viewed, especially when it steps into disputes involving U.S. interests.

Pakistan has sought to expand its diplomatic relevance by offering itself as a channel for dialogue. However, questions over its neutrality could limit how much trust it receives from the parties involved. In diplomacy, perception often matters as much as intent, and that appears to be the central issue in this case.

The controversy also underscores the broader geopolitical competition playing out around Iran, where China, the U.S. and regional powers all have competing interests. For Pakistan, the challenge will be convincing skeptics that its role is independent and constructive rather than an extension of larger power politics.
