China has invested heavily in robotics. The country is a leader in industrial robots per capita and has just hosted the first "World Humanoid Robot Games" in Beijing.

But even before this month, China has been turning to high-profile events to showcase its tech, including a robot half-marathon and dancing humanoid robots during its Lunar New Year’s Eve TV gala, watched by hundreds of millions of people, according to The New York Times.

Homed in the Chinese city of Guangzhou, Zhang said that “The artificial womb technology is already in a mature stage, and now it needs to be implanted in the robot’s abdomen so that a real person and the robot can interact to achieve pregnancy, allowing the fetus to grow inside.”
