The visit to China by Pakistani Prime Minister Shehbaz Sharif this week came at a critical time as delicate negotiations intended to end the US-Iran war continue, almost two months into a fragile ceasefire. President Xi Jinping praised Pakistan’s proactive role as a mediator in the talks, while Sharif thanked China for supporting the push for peace in the Middle East.The four-day tour, which ended on Tuesday, strengthened the long-standing “iron brother” relationship between the two nations. It coincided with the 75th anniversary of diplomatic ties between them.Sharif’s trip followed visits to Beijing by US President Donald Trump and Russian President Vladimir Putin earlier in the month, allowing him to learn first-hand of the latest developments.The visit reinforced the shared commitment of China and Pakistan to the peaceful resolution of disputes, respect for international law and support for a multipolar world.Xi also pledged to continue with major construction projects in Pakistan and to work with the country in areas such as industry, agriculture, the development of talent and artificial intelligence (AI). China will sustain its efforts to help Pakistan develop economically and improve the livelihoods of its people.In keeping with the practice adopted by most visiting state leaders to China, the trip was not limited to talks in Beijing. It began with the prime minister arriving in Hangzhou in Zhejiang province, where he attended a business conference.
