Pakistan has reached an agreement with Iran to ensure the passage of at least one Qatari liquefied natural gas (LNG) tanker through the Strait of Hormuz, Bloomberg reported, citing sources. The tanker crossed the strait with its transponder switched on and is currently en route to Pakistan. The agreement on safe passage through the strait could also extend to other shipments, one of the sources added. Earlier this year, Islamabad reached an agreement with Tehran on the safe passage of several LNG shipments. Since February, Pakistan has been forced to spend over $400 mln purchasing LNG on spot markets to replace supplies from Qatar, the agency noted.
