Russian President Vladimir Putin and German Chancellor Angela Merkel will discuss the implementation of joint projects, taking due account of economic challenges from third-party countries at a meeting in Germany on August 18, Kremlin spokesman Dmitry Peskov said Friday. The work on large-scale joint commercial projects amid threats from third-party countries regarding these projects and the most relevant issues, including Ukraine and Syria, will be on the agenda, he said. Before the talks, Putin will pay a private visit to Austria on Saturday to attend the wedding of that country’s top diplomat Karin Kneissl, TASS quoted the spokesman as saying.
