Germany's Aitamei brand belongs to Germany's Gome Lebao and was first acquired by France's Danone Group. Australia's Rehai milk powder belongs to New Sidi, which was acquired by Danone Group of France after 2007. Therefore, since 2007, Australia's Rehai and Germany's Rehai belong to the brand of France's Danone Group and are brothers. Moreover, after Australia's Keruikang changed its name to Australia's Atami, Germany's Atami milk powder was introduced on the basis of the original formula of Keruikang, which was similar to the formula ratio of breast milk. To put it simply, the Australian version and the German version both belong to the same group, but the formula is slightly similar, and there are still great differences in other aspects.

The Australian version of Aitemei is a New Zealand milk source, and the German version of Aitemei is a Swiss milk source.

Germany loves its finely divided milk powder, Britain loves its most cost-effective milk powder, and Australia loves its best taste milk powder.
