China's deputy representative to the UN, Geng Shuang, told a Security Council session: "The countries involved [Germany, Denmark and Sweden] have already carried out national investigations for a period of time, but the results remain ambiguous. The longer they delay, the harder it will be to gather evidence and uncover the truth, and this will increase suspicion and speculation, and the less credible the results of the investigation." "Russia is one of the parties involved [in the case of sabotage of the Northern Stream lines], and we call on the countries concerned to communicate and cooperate with Russia, rather than refusing to engage with it," Shuang said."We hope that the countries concerned will respond effectively to the concern expressed by the international community and announce progress in the investigations in a timely manner." On September 26, 2022, explosions occurred on two pipelines for the export of Russian gas to Europe "Northern Stream 1" and "Northern Stream 2". Germany, Denmark and Sweden did not rule out targeted sabotage.Northern Stream operator Nord Stream AG said the destruction of gas pipelines was unprecedented and it was impossible to estimate the time needed for repairs. Meanwhile, representatives of the Russian side have repeatedly pointed out that Denmark, Sweden and Germany do not allow Russia to participate in their investigations and deny access to information.American journalist Seymour Hirsch published in his investigation on February 8, citing a source, that explosive devices were planted under Russian gas pipelines in June 2022, under the cover of "Baltups" exercises carried out by US Navy divers with the support of specialists. According to Hersh, the decision to launch the operation was made by US President Joe Biden, after nine months of discussions with administration officials concerned with national security issues.Later, the Pentagon told Sputnik that the United States had nothing to do with the sabotage of Russian gas pipelines.
