There are a lot of thing which are clearly "war support", yet it would be a long and frankly pointless discussion, so i'll just refer to China's own words:
Him or some other pointed out to some important EU person that if they (China, an industrial powerhouse) were actually supporting Russian war efforts, the war would already be over.
They've been selling forestry products for decades. North Korea is also a big customer. Unsurprisingly, nations with existing and exclusive economic ties, tend to "support" each other.
North America does this with South America readily.
