What Does A Foreign Minster Do?

The foreign Minister of any country is responsible for maintaining good terms with all other countries. He receives the dignitaries from other countries and plays a host to them.  He expresses his country's stance on various issues happening in the world and in his country. He always accompanies the head of a state on his/her tours to foreign countries. He is glib and well versed and very diplomatic in his conduct and has to be very tactful to handle the ups and downs in the relationship of his country with other states. He's responsible for bettering the country's relations with other countries through his diplomatic skills.

I believe they preach the words like other Ministers does.
