NEW DELHI/SINGAPORE/TOKYO: US and European pressure on Asian buyers of Russian energy could restrict India’s oil imports from December, leading to cheaper supplies for China, while Japan is unlikely to halt its Sakhalin liquefied natural gas shipments for now, trade sources and analysts said. Washington is exerting pressure on China, India and Japan through trade talks to reduce their purchases of Russian oil and LNG, while Britain has just imposed sanctions on Chinese and Indian entities. More sanctions from the European Union could follow.
