New Delhi, Dec 12 (ANI): The leader of Crimea, the former Ukrainian territory annexed by Russia, visited India as a member of President Vladimir Putin's summit delegation, in a move that is already "troubling" the United States. India does not back Western sanctions against Russia, but the unofficial trip by Sergey Aksyonov could spoil the mood before Prime Minister Narendra Modi hosts US President Barack Obama for Republic Day festivities in January. Aksyonov arrived at the upscale Oberoi hotel accompanied by Russian diplomats to be greeted by Gul Kripalani, a Mumbai-based seafood merchant who wants to boost trade with Russia. Speaking to reporters after signing a memorandum of understanding to promote business, Aksyonov said his visit had "a private character" and he did not take a part in any official events.
