Tens of thousands of conscription-age Russian men have fled to neighboring countries since President Vladimir Putin announced a mobilization of military reserve troops to fight in Ukraine. The tide has grown in recent days amid fears that the Kremlin will impose an exit ban. The sense of a closing window has led to chaotic scenes on Russia's land borders with Georgia, Kazakhstan and Mongolia—countries that do not require a visa for visiting Russians. There has been a particular crush at Russia's sole border crossing with Georgia, where some 3,500 cars have backed up the road for nearly 10 kilometers. (Moscow Times)

Russian energy giant Gazprom cut off the flow of natural gas to Germany and other European markets via the Nord Stream pipeline on Aug. 31, calling it a three-day shut-down for maintenance purposes. But Western governments charge that Russia is "weaponizing" gas supplies amid the Ukraine war. (EuroNews) Days earlier, Germany's government broached allowing the blocked Nord Stream 2 pipeline to begin pumping Russian gas. Wolfgang Kubicki, vice president of the Bundestag, said the move is necessary so "people do not have to freeze in winter and that our industry does not suffer serious damage." His comment prompted a harsh response from Kyiv, where Foreign Minister Dmytro Kuleba said that "addiction to Russian gas kills." (Politico)

Long-depressed oil prices are suddenly soaring in response to the Russian invasion of Ukraine, with impacts already being felt globally. Kazakhstan, recently wracked by internal instability, is facing economic crisis as its crude exports are threatened. Most of these exports pass through a pipeline linking Kazakhstan's western oil-fields to Russia's Black Sea terminal at Novorossiysk. That terminal, owned by the Caspian Pipeline Consortium (CPC), lies within 250 kilometers of the Ukrainian port of Mariupol, now besieged by Russian forces. This proximity is sufficient for tankers loading at the Novorossiysk terminal to incur a "war risk insurance premium." According to S&P Global Platts, the premium has been high enough to deter buyers since the Russian invasion of Ukraine was launched late last month.

Belarus on Feb. 28 voted in a referendum to approve constitutional changes that include dropping the country's nuclear-free status. On the eve of the vote, President Alexander Lukashenko expressed his willingness to redeploy nuclear arms in the country's territory, saying: "If [the West] transfers nuclear weapons to Poland or Lithuania, to our borders, then I will turn to [Vladimir] Putin to bring back the nuclear weapons that I gave away without any conditions." 

The government of Poland announced Feb. 4 that it has agreed to pay compensation in a dispute over the Turów open-pit lignite mine that lies close to the border with the Czech Republic. In return, Prague has withdrawn its complaint at the Court of Justice of the European Union. The dispute concerns the complaints of local farmers on the Czech side of the border that their water sources are going dry due to the mine's operations. The Turów Brown Coal Mine, owned by Poland's parastatal power company PGE, must pump water from the pit into the Lusatian Neisse River, draining the local aquifer. The mine has been expanding closer to the border, further enflaming the fears of the Czech farmers. The deal was protested by Greenpeace for failing to provide sufficient guarantees for protection of the watershed. (EuroNews, Jurist, Expats.cz, BBC News, EUReporter)

Russia's Deputy Foreign Minister Sergei Ryabkov on Dec. 13 warned that Moscow will deploy intermediate-range nuclear weapons if NATO does not accede to demands to stop arming Ukraine and guarantee an end to eastward expansion of the alliance. His remarks came days after US President Joe Biden and Russia's Vladimir Putin held a two-hour video conference aimed at defusing tensions over the Russian military build-up along Ukraine's border, where the Kremlin is estimated to have amassed some 100,000 troops.

Tensions on the European Union's eastern border escalated sharply this week as Polish border guards repulsed a wave of some 4,000 asylum seekers and migrants seeking to cross from Belarus. Poland has mobilized 15,000 soldiers to the region to prevent people from crossing, and Belarusian security forces are not allowing the migrants to turn back. The migrants are sleeping rough as temperatures plunge below freezing; a 14-year-old boy froze to death, becoming at least the eleventh person to have died attempting to cross the border. There are fears the situation could result in a military confrontation.

Thousands marched in Glasgow as the COP26 climate summit entered its second week Nov. 6, demanding ambitious and concrete proposals on limiting global warning to 1.5° Celsius above pre-industrial levels—the lowest target under the 2015 Paris Agreement. Police arrested 21 people, including members of the Scientist Rebellion movement who had chained themselves to the King George V Bridge over the River Clyde in Glasgow's city center. A UN Climate Change Update on Nationally Determined Contributions issued two days earlier found that even with the new pledges made thus far at COP26, emissions are still set to rise 13.7% by 2030. To be compliant with the 1.5C goal, they must fall 45% by that year.
