Shehbaz Sharif's office said the premier had discussed with Qatar's Emir Sheikh Tamim bin Hamad Al Thani "the latest regional and international developments, particularly in the Middle East".

The Qatari ruler praised Pakistan's role and, according to the Pakistani statement, the pair also voiced support for "de-escalation efforts and enhancing international coordination to ensure the security and stability of the region, particularly ensuring the maintenance of smooth flow of energy supply chains".

The official Qatar News Agency later reported the Pakistani premier had left Doha. He was due in Turkey, the last stop in a four-day tour on the heels of high-level talks between US and Iranian delegations in Islamabad last weekend.

The talks in Pakistan failed to reach an immediate agreement to permanently end the war in the Middle East following the start of a two-week ceasefire on April 8.

Immediately after the Doha meeting, Sheikh Tamim headed to Muscat to meet Oman's Sultan Haitham bin Tariq.

The two Gulf rulers "emphasised the necessity of reaching a final agreement and resolving the crisis at its roots", the Omani foreign ministry said in a statement.

Oman had hosted multiple rounds of US-Iran talks before the war cut the process short.

Qatar, a key mediator with the United States and Egypt in the Gaza war which ended in October, has in recent years played a role mediating with Iran alongside Oman.

However, Doha has repeatedly dismissed the possibility of mediation with Tehran after it came under attack on February 28.

Early in the war, sparked in late February by US and Israeli strikes on Iran, Qatar was forced to suspend liquefied natural gas (LNG) production because of Iranian attacks on key energy infrastructure.

The tiny Gulf state, which shares the massive South Pars gas field with Iran, is one of the leading producers of LNG along with the US, Australia and Russia. Qatar is a key supplier to Asian nations including Pakistan.

On Wednesday, the Qatari ruler held a call with US President Donald Trump. A statement from the emir's office said they discussed the impact of the war "on international maritime security and the stability of global energy markets and supply chains".

Trump has indicated that a possible second round of peace talks with Iran in Pakistan could take place this week.
