TAIPEI, Oct 2 (Reuters) – Taiwan sharply criticized China on Saturday after Beijing marked the founding of the People’s Republic of China with the largest ever incursion by the Chinese air force into the island’s air defense zone. Taiwanese fighters scrambled against 38 Chinese aircraft in two waves on Friday, the Taiwan Defense Ministry said. It said Taiwan sent combat aircraft to warn away the Chinese aircraft, while missile systems were deployed to monitor them. The previous largest incursion happened in June, involving 28 Chinese air force aircraft. China has stepped up military and political pressure to try and force Taiwan to accept Chinese sovereignty.
