Possibly a follow-on question (or maybe part of the answer)?

There was a reply in "Why didn't the Japaneese help or aid the Germans against the USSR in WW2, and instead go full on war with the US?", by /u/kieslowskifan at https://www.reddit.com/r/AskHistorians/comments/80lgxq/why_didnt_the_japaneese_help_or_aid_the_germans/duxut3t/ . It notes a divergence between the IJA and IJN after the Russo-Japanese War.

The IJA favored a continental approach with a Japanese-led regeneration of the Chinese and the creation of various imperial satellite states within the East Asian mainland. The navy favored what became to be known as the "Southern Drive" for the natural resources and the seizure of the resource-rich lands of Southeast Asia.

Was that the first cause of the hatred? Or did such hatred exist before, or did it only develop long after?
