Russians have sent 3 Ilyushin planes filled with men and equipment, French have sent boats and men, Czech have sent some special water pump. That's all the info I've got of that kind.
Currently we are facing an even bigger problem, as there is a threat of spillage of water in city of Sabac (Šabac). The issue is that in city of Sabac there is a big Ammonia factory, there is no way to safely empty the tanks and if water floods (water level is just 10cm lower than defensive barriers), and breaches the factory, mixes with ammonia it's could be a disaster of epic scales, half of Serbia, most of Romania and Bulgaria would be left without clean, drinking water, while most rivers and the Black Sea would be seriously contaminated.
