WARSAW, Poland (AP) — A Chinese Navy destroyer, a Chinese frigate and a Chinese supply vessel sailed into Poland's navy port of Gdynia on Wednesday on the first such visit ever, marking 66 years of diplomatic ties and aiming to strengthen them even more. Capt. Maj. Przemyslaw Plonecki, the spokesman for Poland's 3rd Navy Flotilla, told The Associated Press that the flotilla's command officers paid a visit to the destroyer in an official welcoming ceremony.
