Under China's 13th FYP, the GDP growth rate was expected to be average 6.5% but due to pandemic in 2020 the actual GDP growth average is 5.8%. Without 2020, the growth rate is 6.6% which just barely above the growth target.
Under China's 14th FYP, the Chinese government doesn't have a guidance of growth but the expectation is between 5% to 5.5%. China would focus on quality of growth as the government is trying to rein in bubble in property sector. So using per-pandemic growth rate for calculation is just inaccurate.
More importantly, I just don't understand why you expect China's GDP growth to continue to grow at the same pace. As all major developing countries have experienced, GDP growth rate tends to decelerate after reaching certain threshold. China's GDP per capita at $12,840 is approaching high income economy which the world bank sets at $13,845. Therefore, it is more realistic to use 5% to 5.5% average for 2021-2025 to calculate if China met its target or not. Beside, it is the property sector that is the biggest drag to the economy. COVID actually isn't that big a factor.
