"It is absolutely obvious that it is impossible to discuss the signing of such a document (a peace treaty) with a state that takes openly unfriendly positions and allows itself direct threats against our country," Rudenko told TASS in an interview.Russia withdrew from its talks with Japan in March last year, following Japanese sanctions over Russia's invasion of Ukraine.Japan reacted angrily to the talks, calling Moscow's move "unfair" and "completely unacceptable".Separately, Rudenko also said that Russia supports Beijing's "One China" policy on the issue of Taiwan, reiterating Moscow's explicit backing of China over the fate of the island where the defeated Republic of China government fled in 1949."Beijing is well aware that the Russian side invariably supports the People's' Republic of China on the Taiwan issue," Rudenko said."
