30 day visa free travel NEW ZEALAND --> DALIAN --> HARBIN --> VLADIVOSTOK
Hi there.
I am planning travel as a New Zealand passport holder, departing from NZ to Dalian, China. In Dalian I will spend 3-4 days, before taking a bullet train to Harbin, and spending a further 3-4 days in Harbin. After Harbin, I will be taking a bus to Vladivostok.
The bullet train tickets and bus tickets I presume will need to be booked before I first enter China, to show the authorities proof of my purpose of stay in China. However, it would be significantly easier to book them when I am already in China. Can I do such thing?
Also, the travel from Dalian to Harbin via bullet train crosses provinces; in regards to the 30-day visa free policy, is this allowed? How will the authorities at the airport in Dalian be able to confirm that I am indeed carrying out my intended travel?
Finally, if I travel by bus from Harbin to Vladivostok, does this count as private transport? Do I need any documents upon nearing China's border?
Much appreciated,
Marianna.
