“We are working on this,” Pankov said, while declining to elaborate. 

Previously the deputy head of the foreign affairs committee of the Russian parliament, Aleksey Chepa said that Russia “should re-assess the issue of our presence in other regions of the world. I believe that it would correspond with Russian interests to restore the bases in Latin America, Southeast Asia, and Africa that were closed,” as quoted by TASS.

There were Soviet and Russian military bases in Cuba and Vietnam until 2002. The Russian navy was deployed in Cam Rahn, Vietnam, and Russia had a radio-electronic intelligence center in Lourdes, Cuba. The base was the largest of its kind operated by the USSR (and later Russia) outside of the country. 

At the end of 2014, a deal was signed between Russian and Vietnam, setting up standards of use of Russian warships in the port of Cam Ranh. According to the simplified procedure, Russian ships would only have to give prior notice to the Vietnamese authorities before entering Cam Ranh Bay, while other foreign navies would be limited to only one ship visit a year to Vietnamese ports.
