TOKYO -- The escalating global response to Russia's invasion of Ukraine is starting to hit Moscow where it is most vulnerable: the ruble and energy, its top export.
The latest example is Shell's announcement on Tuesday that it will divest its 27.5% stake in the Sakhalin-2 energy project. The move follows Germany's halting of the Nord Stream 2 gas pipeline and BP's announcement that it will sell its 20% stake in Russian state-owned oil company Rosneft.
