"The commission will start online preparations for a ministerial meeting which is currently planned to be held before the end of the year," the diplomatic source told TASS on Tuesday.
It is expected that the ministerial meeting will also be held online due to the coronavirus restrictions, the source added.
The meeting of the JCPOA Joint Commission at the level of political directors was initially planned to be held in Vienna on December 16, however, it was later moved online.
The delegations of the remaining parties, namely Iran, China, Russia, the UK, France and Germany will speak remotely from the capitals of the parties to the deal. The meeting will focus on further steps to implement the JCPOA.
