international transit without entry - passport validity less than 3 months
I will be flying with China Southern Airlines from Tokyo Haneda Airport (Japan) to Frankfurt Airport (Germany), with a layover at Guangzhou Baiyun Airport. The duration of my layover in Guangzhou will be about 9 hours.
I do not intend to enter the country, nor will a new check-in be necessary, as the airline will handle the check-in process at the departure airport in Tokyo.
My European passport (German nationality) is only valid for another month, so it falls short of the commonly required three-month passport validity period for transiting through Guangzhou.
Given these circumstances – that I will remain in the sterile transit area and will not pass through immigration – I would like to ask whether I can proceed with my planned journey under the current conditions or if there will be any problems?
Thank you very much in advance for your assistance.
