Hi@akhtar,
You can use LocationConstraint in your command. The following command creates a bucket named bucketnew in the ap-south-1 region. Regions outside of us-east-1 require the appropriate LocationConstraint to be specified in order to create the bucket in the desired region.
$ aws s3api create-bucket --bucket my-bucket --region ap-south-1 --create-bucket-configuration LocationConstraint=ap-south-1
