According to our data, at 15:37, Bombardier Global 5000 (reg. number PA-9834) landed at Minsk National Airport.
This plane is used by the government of Pakistan, but it’s unknown who exactly arrived in Belarus from Pakistan and for what purpose.
However, we may assume that these were observers for the CSTO drills Combat Brotherhood-2023, which will be held in Belarus from September 1 to September 6. For example, in 2021, observers from Pakistan were in Belarus during the West-2021 drills.
