Final answer:
China has a complex stance on information transparency, with a history of censorship and government control. Despite this, it engages with the global community through projects like Breakthrough: Starshot. Specific measures for transparency in space activities weren't provided, but it can be presumed that such information is tightly controlled.
Step-by-step explanation:
The question pertains to the measures China takes to ensure transparency in its outer space activities. Given China's history with issues of transparency and freedom of information, as detailed in the provided references, it is clear that China maintains a level of control over information dissemination within its borders. This control extends to different aspects of Chinese society, ranging from Internet censorship to the dissemination of information regarding air quality levels in cities such as Beijing.
Additionally, China upholds its constitutional commitment to privacy in communication, yet the interpretation of this right is often narrow. Despite the tight control over the flow of information, the Chinese government cannot completely shut down the spread of information, exemplified by the fact that foreign companies and the government itself utilize platforms like Weibo to engage with the public.
When it comes to China's space activities, they have contributed to international projects like Breakthrough: Starshot, aiming to send miniature spacecraft propelled by powerful lasers to planets like Alpha Centauri. However, there is no explicit mention of measures China takes to ensure transparency in these activities. Considering China's overall approach to information control, one can reason that while some space-related information might be shared with the global community, especially in collaborative efforts, details regarding China's space missions and goals may be closely guarded within the framework of its national interests and security policies.
