According to the propaganda, there are diplomatic envoys and wives from more than 20 countries on five continents participating in cultural exchange activities, which is not a matter of one country, so:

1. Diplomatic envoys in China visit Cangnan

If it is a slogan, banner: Welcome the diplomatic corps to visit Cangnan.

2. The activities of diplomatic envoys in Cangnan.

Since it is put on the logo, it should be short and pithy, preferably in all capitals, and choose a solemn font. The special envoy's trip to Cangnan should be commercial, diplomatic and political, and the visit is more appropriate. Travel is not suitable.

Ambassador, the highest-ranking diplomatic representative

A special envoy, or a diplomatic representative after an ambassador.

Diplomat = general term, diplomat, such as ambassador

Diplomatic mission = diplomatic mission (all diplomatic envoys in capitals)

For example, British Ambassador to Greece = British Ambassador to Greece (from Oxford Modern Advanced English-Chinese Dictionary, 3rd edition).

I hope it helps.
