For this relationship, when Pakistan is in trouble, Saudi Arabia must lend a helping hand. After all, the lips are dead and the teeth are cold. Moreover, Saudi Arabia chose to invest US$ 654.38+0 billion in the China-Pakistan Economic Corridor to build an oil refinery, which has great returns and great significance-not only can it expand its oil exports to the world's second largest economy (Saudi Arabia has to make great efforts to compete with Russia and Iran for the market share of the world's largest oil importer). At the same time, expanding the diplomatic scope, trying to get rid of the control of the United States, diversifying its own investment, and choosing Pakistan to strengthen its ties with China.

On military and nuclear issues, Saudi Arabia and Iran also want to benefit from Pakistan.

Saudi Arabia needs military support from Pakistan. For decades, Pakistan has maintained more than 1 10,000 troops in Saudi Arabia. Helping to train Saudi soldiers and guide them to fight has long been the most important foundation and guarantee of Sabah friendship. In the past two years, Saudi Arabia and Iran have been fighting proxy war in Yemen, but it was the Pakistanis who helped Saudi Arabia get out of trouble.

For Iranians, their military strength is much stronger than that of Pakistan. Naturally, they don't want Pakistani soldiers. They want more important nuclear technology. Pakistan is currently the only Islamic country that has been recognized as possessing nuclear weapons. The nuclear secrets passed to Iran before probably came from Abdul Qadir Khan, the former chief nuclear scientist of Pakistan, and Iran's centrifuge project also benefited from Pakistan's design.

The above is my personal opinion.
