Plz help me it's urget. How can diplomatic mossion increase the reputation of the country?

Diplomatic mission mostly carried out in order to provide some sort of aid to another country for their situation or to establish a mutually beneficial relationship with one another.

Series of diplomatic missions will slowly strengthen our relationship with another country and improve the citizens' perspective toward our own country.

This will increase the likelihood of us establishing a strong alliance with that other countries in case we're in the position that need their help in the future.

the answer would be in this answer. someone already asked the question.  

question - in 1827, john walker, a druggist in a small english town, tipped a splint with sulphur, chlorate of potash, and sulphid of antimony, and rubbed it on sandpaper, and it burst into flame. the druggist had discovered the first friction-chemical match, the kind we use to-day. it is called friction-chemical because it is made by mixing certain chemicals together and rubbing them. although walker's match did not require the bottle of acid, nevertheless it was not a good one. it could be lighted only by hard rubbing, and it sputtered and threw fire in all directions. in a few years, however, phosphorus was substituted on the tip for antimony, and the change worked wonders. the match could now be lighted with very little rubbing, and it was no longer necessary to have sandpaper upon which to rub it. it would ignite when rubbed on any dry surface, and there was no longer any sputtering. this was the phosphorus match, the match with which we are so familiar. according the paragraph what was the benefit of the new phosphorus match? it burst into flame when rubbed on sandpaper. it was made by mixing chemicals. it could be ignited on any dry surface. it threw fire in all directions.

answer - matches required natural chemicals
