STEPANAKERT, Azerbaijan — On a crystalline spring morning, Iosif Adamyan sipped coffee on the veranda of his guesthouse, overlooking a pear orchard in bloom and, in the distance, a range of snowy mountains.

In this picturesque spot, he entertains guests from England, France and Russia; in fact, people from “the whole world,” wind up here, he said, with the peculiarity that many of them speak Armenian.

At the stately Hotel Armenia, which caters to the diaspora visiting the capital of the disputed mountain enclave of Nagorno-Karabakh, dear to the hearts of Armenians everywhere, the dining room clings to the traditional starched tablecloths and, of course, aged Armenian cognac.
