Where does China get helium?

Where does China primarily obtain its helium supply? Given the scarcity of this element, it's intriguing to know if China relies on domestic production, imports from other countries, or perhaps a combination of both? Given China's status as a global economic power, does it have significant helium reserves within its borders, or does it face challenges in securing a stable supply chain? It's also interesting to ponder whether China's helium procurement strategies align with its broader economic and technological objectives. Could there be any potential opportunities or challenges in this domain for China's future development?
