After a decades-long infrastructural boom, China has produced numerous world-leading infrastructural projects: China has the world's largest bullet train network, the most supertall skyscrapers in the world, the world's largest power plant (the Three Gorges Dam), the largest energy generation capacity in the world, a global satellite navigation system with the largest number of satellites in the world, and has initiated the Belt and Road Initiative, a large global infrastructure building initiative with funding on the order of $50–100 billion per year. The Belt and Road Initiative could be one of the largest development plans in modern history.
