　　Japanese Prime Minister Sanae Takaichi claimed on Wednesday there was room for discussion regarding the wording of the "no introduction" clause under Japan"s Three Non-Nuclear Principles as Japan plans to revise its three key security documents by the end of this year, a move that has drawn concerns over whether Japan is seeking to loosen its long-standing nuclear policy constraints, a Chinese expert said.

　　The expert noted the move is "an attempt to conceal its true intent" and reflects a dangerous signal that Japan is seeking to dismantle its postwar nuclear policy restrictions, which is unacceptable, and warned that any weakening of the "no introduction" principle could hollow out Japan"s non-nuclear policy, open the door for US nuclear weapons to enter Japan, and bring risks to peace and stability in Northeast Asia.

　　According to Japanese media TBS News, Takaichi made the claims at a meeting on Wednesday, saying that while the government is discussing the revision of the three security-related documents, the specific wording of the "no introduction" principle is still under consideration. She also referred to the concept of US extended deterrence, saying these issues deserved consideration, while declining to predict the final wording.
