Eastern Europe and the Baltics. Too much historical and ideologic baggage to play all sides and stay non-committed to anyone as China usually tries to do.
There are some countries were trying to deal with them and the benefit they might bring, isn't really worth the hassle. The baltics are a few of these countries.
Their economy is rather small thus with limited potential, most of their industries that wasn't left by the Soviets just revolves around license building stuff by others but cheaper compared to other parts of europe, so they don't offer anything you can't find anywhere else other than more Waffen SS memorials per capita
It's probably better to just wait until the writing is on the wall for the end of the US as an hegemon that the Baltics will chill the f* out to deal with them.
