Britain's Call for Free Navigation

London: On Monday, the UK emphasized the need for a permanent resolution to guarantee free navigation and a toll-free Strait of Hormuz, as the ceasefire between the US and Iran remains uncertain.

UK Foreign Secretary Yvette Cooper is currently in Japan, concluding a significant diplomatic tour aimed at enhancing collaboration with key allies on geopolitical, economic, and energy security matters.

Throughout her six-day journey across Europe and West Asia, Cooper engaged in discussions with Foreign Ministers from 11 nations, including Pakistan, Turkey, Egypt, the UAE, and Ukraine, culminating in a meeting with Japan's Foreign Minister for the annual Strategic Dialogue in Tokyo.

Following her meeting with Pakistan's Foreign Minister Ishaq Dar, Cooper remarked on the critical need to extend the ceasefire and fully reopen shipping routes through the Strait of Hormuz.

She expressed gratitude towards Pakistan for its role in facilitating diplomatic discussions.

This diplomatic push comes in light of the US's recent seizure of an Iranian cargo ship in the Strait of Hormuz, which was allegedly attempting to bypass the American blockade on Iranian ports. This incident has disrupted planned negotiations in Pakistan, as Tehran has opted out of the peace talks.

Cooper highlighted the urgency of the situation, stating, "This is a crucial diplomatic juncture with the ceasefire nearing its end. Further discussions for a lasting resolution are essential, and they must ensure a toll-free Strait of Hormuz."

She noted that Iran has proposed implementing tolls on the Strait once the conflict concludes. Since convening a call with over 40 nations in early April, efforts have been underway to forge an international consensus on the necessity of reopening the Strait of Hormuz and restoring unrestricted freedom of navigation.

Cooper emphasized that many countries are aligning with the UK in asserting that a sustainable resolution cannot involve the Iranian regime imposing charges for access.

Continuing her discussions in Japan, she stressed the importance of setting a positive precedent for global navigation rights.

She warned that establishing a negative precedent in the Strait of Hormuz could severely impact both the global economy and security, making it imperative to win this argument.

The Foreign, Commonwealth and Development Office (FCDO) announced that Japan has joined the UK's initiative to support the resumption of free passage in the Strait of Hormuz. Recently, Japan has also unveiled a new cooperation framework with its Asian partners, pledging USD 10 billion in financial assistance to help neighboring countries, particularly in Southeast Asia, secure energy resources.

The UK has been actively engaging with global partners to build a broad coalition against tolls, including organizing a summit in France last week with 50 countries, including India.

The Foreign Secretary has made it clear that coordinated international efforts are essential to prevent individual nations from jeopardizing the global economy, protect supply chains, uphold international law, and maintain a rules-based order.
