Pakistani schoolchildren learn the slogan before they learn the map: Pakistan-China friendship is “higher than the Himalayas, deeper than the oceans, sweeter than honey.” Behind the poetry is the hardest-headed relationship in Pakistan’s foreign policy — the one alliance that has survived every war, every government and every sanctions regime since 1951.
Quick answer: China is called Pakistan’s “iron brother” (巴铁, bā tiě) because the partnership spans everything: the $62 billion China-Pakistan Economic Corridor, co-production of the JF-17 Thunder fighter, the Karakoram Highway, and decades of diplomatic cover at the UN Security Council and FATF. Diplomatic relations were established in 1951; the “all-weather” label dates to the 1960s.

The four pillars of the friendship
- Economics: CPEC — roads, power plants, Gwadar port, the ML-1 railway upgrade — is the largest foreign investment programme in Pakistan’s history.
- Defence: the JF-17 Thunder multirole fighter (co-produced at Kamra), F-22P frigates, submarines on order, and regular Shaheen joint air exercises.
- Diplomacy: China has used its UN Security Council weight for Pakistan repeatedly — on Kashmir consultations and against India-sponsored listings — and stood with Pakistan at the FATF in 2018.
- People: tens of thousands of Pakistani students study in China; Chinese workers built the projects Pakistanis drive on. The affection is genuinely popular, not just official.
CPEC: the $62 billion bet
Announced during President Xi Jinping’s 2015 visit to Islamabad at $46 billion and later expanded past $62 billion, the China-Pakistan Economic Corridor links Kashgar to Gwadar: energy projects that ended Pakistan’s worst load-shedding, the Karakoram Highway’s rebuild, motorways, fibre optics, and Gwadar port — giving western China its shortest route to the sea. Phase two pivots to agriculture, industry and technology transfer. Critics cite debt and transparency; supporters cite the power plants that kept the lights on.
Defence: from Karakoram to JF-17
The military bond predates CPEC by decades: China supplied Pakistan through the 1965 and 1971 wars and the sanctions years that followed. The Karakoram Highway (completed 1979) was built with Chinese engineering and Pakistani labour. The JF-17 Thunder — designed jointly, built at Pakistan Aeronautical Complex, Kamra, and combat-proven — is the partnership’s signature product, now exported to multiple countries.
Tests the friendship survived
The 1962 Sino-Indian war (Pakistan stayed neutral-friendly), the 1971 war, the post-1998 sanctions, the US “war on terror” years, the 2018 FATF battle, and the 2025 India-Pakistan crisis — in each, Beijing’s support held while others wavered. That record is why “iron brother” is not just a slogan in Islamabad.
