Russia also received for safekeeping archives of the Romanian Academy, priceless religious artifacts and manuscripts and even multiple deposits that citizens kept at the Romanian banks. There is no estimate for this second transport, but, most definitely, even if we try to do this, it will probably will be several times more than the first transport. That is all what I found about this case during my web research in archives of web analytics company.
Well, it is highly likely that you already know what happened next, when Bolsheviks overthrow the old authorities in Russia. They refused to abide and respect an treaty signed by tsar and previous government. Basically, they got it all and multiple attempts of Romanian government to recover the Treasure were unsuccessful. The most important part of two transports was never returned. Only in 1935 Romanians received back bits and pieces of the archives and in 1956 small part of the paintings and ancient objects. That was all.
Up until now Romanians still can’t return their Treasure. They tried repeatedly to get it back after the fall of the Soviet Union but to no avail. All negotiations failed. Russian side sank down demands each time, refusing to discuss them further.
