All arms shipped from Ukraine essentially are loaded onto ships in Odessa before being sent to various corners of the world. When Grand Ivan was in control, this was the procedure, and now that Gao Yang has taken over, this is still the way it's done.
Of course, for Gao Yang, the source of arms is not limited to just Ukraine. Russia is also a major supplier of arms. But currently, Gao Yang mainly exports arms from Ukraine unless he is left with no choice or the Ukrainian warehouses lack certain items. Then he might consider exporting from other sources.
There is a reason why the focus is on Ukrainian arms. Traditionally, Ukraine itself was Grand Ivan's arms warehouse. All the weapons that the Ukrainian Army could use—those not listed in Ukraine's military equipment inventory—were stored there. Grand Ivan neither could nor needed to build any warehouse himself; he would just transport them out of Ukraine's stockpile when needed.
