Yoon had been pushing for it, yes; the agreements (as in, concrete steps having been taken) were announced bilaterally so I don't think that none of it was Kishida, especially as this happened extremely close to Kishida's announcement regarding Japan's defense budget. Either way, my original response will be edited to reflect this.

That's correct, but it takes two to make an agreement, and much of the LDP's leadership is likely to pander to the uyokus. Consider that initially, Korea considered both Kono and Kishida as terrible options, in regards to their relationship, with Kishida being the worst option.

So yeah, I'm impressed that he managed to do so many positive things, given the expectation.
