The Fujian can only operate at just about 60% of the rate of the Ford because the aircrafts landing on the debt rolls over one of the catapults. The angled deck of the Fujian is less than American carriers like the Nimitz or the Ford class.
As it has been written by many people in the past, the USN, Marine Nationale, and PLA Navy practice cyclical operations, so it doesn't matter that the landing strip overlaps with one of the catapult launch positions, because simultaneous launch and recovery are not done as part of normal practice to begin with.
There are so many active and former USN naval aviators who have said this over the years that I am astounded that CNN managed to find retired officers who made such a cliched remark.
The point of cyclical operations is that for a launch cycle you have the flight deck laid out to launch a set number of aircraft (including bow and waist catapults -- which of course overlaps the landing strip), and then for a recovery cycle you clear the landing strip and recover and spot the previous cycle of aircraft which were launched. Rinse and repeat.
Of course, CV-18 would have a lower sortie rate than say, Ford, by virtue of being a smaller ship and having one fewer catapult, one fewer elevator, and other design features that a CVN gets to benefit from versus a CV (smaller island, island positioning etc) -- but one catapult launch position overlapping with the landing strip is not really a major factor.
