Presently, more than 20 countries have backed Guaido as Venezuela's legitimate president.
On Monday, European countries including Britain, Spain, France, Germany, Sweden and Denmark all joined the growing list of those in favour of Venezuela's opposition leader, after a deadline for Maduro to hold fresh elections expired.
However, in addition to the critical support of Venezuela's military elite, Maduro has maintained the support of countries including: China, Russia and Turkey.
"China has been very pragmatic. It's support for Maduro is limited and conditional," IHS' Moya-Ocampos said.
"Russia will also be very careful. It sees Venezuela as an area to pressure the U.S. — but beyond public statements, we are not going to see support in terms of cash and military actions (from Moscow or Beijing)," he added.
