Chinese President Xi Jinping usually uses Boeing 747 passenger planes provided by Air China as special aircraft during his foreign visits. These planes are specially modified to meet safety and service requirements, embodying the principle of strict economy. This arrangement not only ensures the safety and comfort of the leader's travel but also follows the fine tradition of diligence and frugality. China does not have dedicated aircraft for leaders; instead, it adopts the method of temporarily modifying civil aviation passenger planes, which is different from the practice of some countries that have fixed special aircraft.
