Combining the political name of a state with geographical names of other states appears communicatively unsuitable, stylistically clumsy, mannered, and undiplomatic
From the "The opinion of geographers, linguists, historians, and other experts in science and humanities (Charles University, Prague, January 1998)
The one-word geographical name, used in Czech (Česko), should be appropriately translated by a one-word geographical one. If it is translated by the political name "the Czech Republic“, it leads to an undesirable and erroneous shift of the meaning
Eva Horová, linguist - The public hearing in the Senate of Czech parliament, May 11, 2004
It is not possible to say that “..at the beginning of the 15th century, the Hussite revolution broke out in the Czech Republic”. This one could break out only in Czech lands or in Czechia. The book called "History of France" can treat the whole historic period, the book called "History of the Czech Republic" only the history of Czechia (Czech lands) since 1968. This fact as well shows the need of an abbreviated one-word name of the state, which would be universal in time and in space.
Leoš Jeleček, geographer : On the geographic name of the Czech Republic (1999)
If the state authorities had taken care of promotion of their own country from the very beginning, similar to other countries which arose from desintegration of former communist federations, the public would have soon taken into account that the well established "trade mark" Czechoslovakia continues as Czechia, and there would be nothing to discuss today.
Pavel Krejčí in the article Don't be affraid of Czechia, it needs your help! (2008)
A one-word name of the state represents permanency and timelessness of the statehood, regardless of political structure. Using only the political name represents all we do not want - transiency, instability and historical discontinuity.
Vladimír Hirsch to "Businessmen versus linguists", Hospodářské noviny, September 10, 2004
...The awkwardness which surrounds the name of our country in international media and foreign speech has handicapped us. We do not relize it, but irritation, disrespect, and misperception of the Czech geographical and political reality underlie this awkwardnes. Czechia belongs on the map of Europe; the history of Czechia and the Czechs is much longer than the history of our republican state system.....

If Hitler is to make good a nationality claim to Danzig he should first withdraw from Czechia….
