Under what challenging conditions was the ex-soldier arrested in China for espionage?

The ex-soldier was arrested in a remote part of China where the terrain is considered treacherous and impassable, making the operation particularly difficult. The arrest was further complicated by heavy snowstorms during winter that created harsh conditions for the security forces conducting the operation. While the Ministry did not disclose many details about the suspect, they highlighted the geographical challenges faced during this sensitive counter-espionage operation.
