Some images from various aviation suppliers. It's a pity that very few people bother taking photos of these out-of-the-way booths, where information can be gleaned that's just as important –– often more important –– than the glamorous displays of shiny new systems.

Various alloy powders used for fabricating turbines:

Almost thought these displays weren’t put up this year.

Well the typical 052Ds could achieve up to 31 knots (usually around 30) when using the QC280 gas turbine engines with two diesel engines (Chinese derivative of MTU). I don't see the rationale behind putting inferior gas turbine or diesel engines for export vessels. Those two engines are not top secrets for China. The US exports the military version of LM2500 all the time (even to China before 89, and the PLAN Qingdao still uses it). The only plausible reason for the export version of 052D to have two knots down with regards to top speed could be due to more radars and other heavier equipment onboard. So I would expect the full displacement of the Whale Shark to be higher than the PLAN's 052Ds.
I believe that 28 knots is close to the actual top speed of Type 052D(L) class of ships. These ships have effectively the same propulsion output as the Type 052B, a 6.2-6.5 kt full displacement vessel but displace significantly more at 7.7 kt:
