China will launch its second experimental space laboratory late Thursday and another manned space mission next month, the government said, part of a broader plan to have a permanent manned space station in service around 2022.

Advancing China's space program is a priority for Beijing, with President Xi Jinping calling for the country to establish itself as a space power, and apart from its civilian ambitions, Beijing has tested anti-satellite missiles.

China insists its space program is for peaceful purposes, but the U.S. Defense Department has highlighted its increasing space capabilities, saying it was pursuing activities aimed to prevent adversaries from using space-based assets in a crisis.
