Many countries have, over the past few weeks, taken a "wait and see" approach to relations with the US government under President Donald Trump, perhaps none more so than Venezuela.

Venezuela's relations with the US have been contentious for much of the last 20 years, but Venezuelan President Nicolas Maduro appears to hold out some hope ties could be better with Trump.

In recent days, however, that hope seems to be fading.

Venezuela has been close to Russia under Vladimir Putin, whom Trump has spoken highly of, and this week, when the US slapped sanctions on Maduro's vice president, Venezuela's response appeared to avoid mentioning Trump by name, perhaps in an effort to keep open the possibility of improved dealings.

Those sanctions, and the case supporting them, were developed under the Obama administration, but their implementation was held up during the final months his presidency.
