(ANSA-AFP) - WARSAW, OCT 3 - Warsaw and Kyiv announced Tuesday they had agreed to speed up the transit of Ukrainian cereal exports through Poland to third countries, a first step in resolving their "grain war". "From tomorrow, grains that transit (to world markets) via Lithuania will undergo checks at a Lithuanian port and not at the Poland-Ukraine border," Polish Agriculture Minister Robert Telus told journalists, calling it an "important issue".
