Everyone's idea is actually quite simple: to address the pain points of the Tang Empire landing fleet attacks, there are merely two solutions. The first is to strengthen coastal defenses. The second is to build a capable navy.
The Tang Country's weapon exports perfectly hit these nations' pain points. How could they not be excited? It's like someone delivering a pillow when you're sleepy—there's an undeniable "sending charcoal in snow" feeling to it.
In the eyes of these countries' envoys, the Tang Country is clearly eager to dispel hostility and concerns among nations to maintain a peaceful trade environment.
If the entire world were to fear and be on guard against the Tang Empire, harming relations between nations, it would obviously be detrimental to the Tang Empire.
