Relations with Britain
Recent annexation of Khiva and Bukhara was not well liked in London. London, allready for decades in race with Russia for influence in Central Asia has seen that as another proof of russian expansionist designs for Central Asia and Afghanistan, and later for western China and maybe India.
So, allready not so good relations deteriorated further.
Nicholas was pretty worried because of this, he didn't wanted conflict with Britain now, but on the other hand he didn't want to allow their meddling in Central Asia.
After consultations with Witte and other ministers and generals, they decided that negotiations with Britain are the best solution, but that any major Russian concession would have to be well payed by Britain.
So Nicholas ordered that russian ambassador in London baron Egor Egorovich von Staalb ( he vas ambassador there from 1884 ) be replaced with new ambassador that will be his envoy for talks about Anglo-Russian understanding.
Old ambassador in Netherlands Karl von Struve was named as a new ambassador of Russian Empire in Court of St. James.
He was instructed to carry a Czar's letter to Queen Victoria where he calls her and British Goverment headed by new Prime Minister Robert Cecil, Marquess of Salisbury for a Anglo- British talks about settling open issues between two Empires.
