“Russia is now so deeply invested in the Maduro regime that the only realistic option is to double down,” writes senior fellow at the Carnegie Moscow Center Alexander Gabuev.

He details in a Financial Times op-ed that Moscow-based state oil giant Rosneft owns two offshore gas fields in Venezuela and further has "stakes in assets boasting more than 20m tonnes of crude." But as embattled President Nicolas Maduro faces US-led efforts to oust him in favor of opposition leader Juan Guaido, billions are on the line for Moscow making its interest in preserving the regime run deep.

in 2017 Caracas awarded licenses to Russian oil giant Rosneft for the development of two offshore gas fields, via Reuters.

In total Caracas owes Rosneft $3 billion, according to Gabuev, which could lead to "a new sort of proxy conflict in America’s backyard," which is at once economic, political, and could increasingly turn to proxy military intervention. Indeed the Kremlin has already accused the US of "meddling" in the affairs of a sovereign country in order to foster a "slow motion coup".

"Any solution to the internal political crisis in Venezuela is possible only by Venezuelans themselves," Kremlin spokesman Dmitry Peskov said on Monday. "Imposing any solutions or efforts aimed at legitimizing the attempt of usurping power is, in our view, just direct and indirect meddling in Venezuela’s internal affairs," Peskov said.

"This does not contribute in any way to the peaceful, effective and vital settlement to the crisis, which Venezuelans are enduring and who should, as we believe, pull through it on their own," the Kremlin spokesman noted.

This comes after a significant weekend development in which US National Security Adviser John Bolton promised that the United States will begin humanitarian aid shipments into Venezuela via Brazil and Colombia, despite Maduro denying acceptance of such aid. Guaido, considered "Interim President" by Washington has "authorized" such aid.

But as Gabuev suggests in FT, Rosneft's powerful Chief Executive Igor Sechin's involvement in decision-making on Venezuela means Moscow's foreign policy is “increasingly driven by a combination of corporate interests and ambitions” led by Putin's oligarchic inner circle. According to Gabuev, Sechin met Maduro in Moscow last September and followed that by flying to Caracas in November. Sechin is “arguably the most powerful man in Putin’s entourage” and oversees Russia's energy sector.

In November Sechin relayed a strong message to Caracas, rebuking the Maduro government over delayed oil shipments designed to repay loans. Reuters reported at the time that:

Sechin and a large delegation of executives met with officials at PDVSA in a Caracas hotel this week. Sechin also met with Venezuela’s leftist leader Maduro, and chided him overoil-for-loans shipments that are behind schedule. “He brought information showing that they were meeting obligations with China but not with them,” said one source with knowledge of the talks.

Meanwhile, both China and Russia further remain the Latin American country's biggest arms suppliers. And as both countries have billions in oil-for-credit type unpaid loans on the line, neither is likely to give up on Maduro so easily.

“Russia and China are using Venezuela as a proxy conflict to challenge the U.S. This is more than just economic support. Russia and China are leveraging its economic support to establish a military-industrial presence in Venezuela,” Joseph Humire, executive director of the Center for a Secure Free Society, told Fox News recently.

All of this suggests amidst what some analysts have dubbed "a new Cold War" scenario that another Cuban Missile Crisis in America's backyard could be around the corner.
