like all of the other ships, it's Chinese design. You have to remember that China is building huge oil tankers these days, so 20K tonne supply ships and 18K tonne LPDs aren't out of their reach at all.
According to one of the specs:
normal displacement: 12.3K tonnes
maximum displacement: 17.6K tonnes
HHQ-7 for air defense
2 Z-8 copters
4 LCAC

According to the people on CDF, the first one is under construction in one of the Shanghai's shipyards.
