In 1978, Japan allowed China Airlines to return to Tokyo International Airport at Haneda after relocating all other airlines at the New Tokyo International Airport at Narita, leaving China Airlines as the sole international operator at Haneda, which at the time was an exclusive domestic facility, the premise being that air carriers from the PRC and Taiwan were prevented from crossing paths at any Japanese airports. Eva Air joined China Airlines later on, although both eventually moved to New Tokyo (now Narita International), with CAL moving on April 18, 2002.
