Hello. I again need your grammar help and will be very grateful for it.

Please tell me if the sentences are OK:
"This is a very difficult situation,
1)the same as in Greece.
2)the same as it is in Greece.
3)the same as that in Greece.
4)the same as the one in Greece.
5)like in Greece.
6)like it is in Greece.
7)like that in Greece.
8)like the one in Greece.
I'll be very grateful for your help.

All of these are correct.

In very formal writing, though, numbers 5 - 9 are usually not used.
