The blessings of the Gospel are available to every nation and people on earth, provided they abide by the covenants set out in the Book of Mormon.
IOW, every nation can be "this land."
“Wherefore, this land is consecrated unto him whom he shall bring. And if it so be that they shall serve him according to the commandments which he hath given, it shall be a land of liberty unto them; wherefore, they shall never be brought down into captivity; if so, it shall be because of iniquity; for if iniquity shall abound cursed shall be the land for their sakes, but unto the righteous it shall be blessed forever.” - 2 Nephi 1:7

(2 Nephi 30:8–9)

29 And they shall go out from all nations; and they shall not go out in haste, nor go by flight, for I will go before them, saith the Father, and I will be their rearward.
(3 Nephi 21:28–29)
29 And it shall come to pass, when the Lord seeth fit in his wisdom that they shall minister unto all the scattered tribes of Israel, and unto all nations, kindreds, tongues and people, and shall bring out of them unto Jesus many souls, that their desire may be fulfilled, and also because of the convincing power of God which is in them.

6 Behold, verily I say unto you, for this cause I have sent you—that you might be obedient, and that your hearts might be prepared to bear testimony of the things which are to come;
7 And also that you might be honored in laying the foundation, and in bearing record of the land upon which the Zion of God shall stand;
8 And also that a feast of fat things might be prepared for the poor; yea, a feast of fat things, of wine on the lees well refined, that the earth may know that the mouths of the prophets shall not fail;
9 Yea, a supper of the house of the Lord, well prepared, unto which all nations shall be invited.
10 First, the rich and the learned, the wise and the noble;
11 And after that cometh the day of my power; then shall the poor, the lame, and the blind, and the deaf, come in unto the marriage of the Lamb, and partake of the supper of the Lord, prepared for the great day to come.
(Doctrine and Covenants 58:6–11)
