China threatens death penalty for 'diehard' Taiwan separatists

China threatens death penalty for extreme cases of Taiwan independence separatists, despite lack of jurisdiction. China plans to punish separatists severely and defend national unity. The new guidelines, based on existing laws, allow for military action against Taiwan if it secedes. Chinese official warns of death penalty for secession crime. Taiwan government is yet to respond. Previous legal measures against Taiwanese officials had little effect due to lack of jurisdiction.
