A total of 55 commodities vessels crossed the strategic waterway between May 11 and 17, according to data from maritime tracking firm Kpler as of Monday morning.

That marked a sharp increase from the previous week, when just 19 vessels crossed -- the lowest weekly figure since the first US-Israeli strikes on Iran on February 28, which led to widespread disruption of traffic through the strait.

Iranian state television said Friday the Revolutionary Guards were allowing more ships to transit the strait, after reporting a day earlier that "more than 30 ships" had been permitted to pass.

Despite the increase, last week's crossings remain broadly in line with wartime averages.

Since March 1, Kpler has recorded 663 commodity vessels transiting the strait, 55 per week on average.

Around half the tankers crossing last week carried liquids.

These included three very large crude carriers, reportedly bound for China, Oman and Japan.

Kpler data also showed 15 dry bulk commodity vessels and 16 liquefied petroleum gas (LPG) tankers crossed the strait last week.

Only one liquefied natural gas tanker carrying Qatari gas to Pakistan crossed, on May 12.

That brought the total number of LNG tanker crossings since the start of the war to eight.

In peacetime, the Strait of Hormuz handles roughly a fifth of global oil and LNG shipments, as well as other major commodities, including fertiliser.

Iran has repeatedly warned that maritime traffic through the shipping lane would "not return to its pre-war status".

On Monday, Tehran announced the creation of a new body to oversee the strait and charge vessels for transiting the waterway, which Iran has reportedly been doing since early on in the war.

- Chinese vessels crossing -

Iranian officials said on Thursday that Chinese vessels had been allowed to transit, after a slowdown the previous week.

According to Kpler, only three commodities vessels linked to China through their flag, ownership or cargo crossed the strait last week.

Two additional Hong Kong-flagged vessels also transited and were heading to Oman and the United Arab Emirates.

The data may not provide a complete picture, however, as vessels do not always disclose final destinations while crossing.

Traffic through the strait since the start of the war has depended on nationality, with Iran saying on Monday that countries complying with US sanctions against the Islamic republic would face difficulties crossing.

Since the start of the conflict, China and India have been among the most frequently reported non-Gulf destinations or departure points for commodity carriers transiting the strait.

Other non-Gulf destinations listed in Kpler's shipping data include Brazil, Pakistan, Thailand and Malaysia, while relatively few vessels reported Western countries as destinations.

Iran's control of the Strait of Hormuz remains one of the central issues in stalled negotiations with the United States, which have yet to produce a breakthrough.
