An international land border is any wet or dry part of a borderline which is located inside a country's territorial waters (if any). The baseline, or the limit between "dry land" and "territorial waters", is the low-water line along the coast. 

Longest land border of a country: 

1. People's Republic of China:  22,113 km
2. Russian Federation: 20,017 km
3. Brazil 14,691 km
4. India 14,103.1 km
5. United States of America 12,034 km
6. Kazakhstan 12,012 km
7. Democratic Republic of the Congo 10,730 km

Longest borders between two countries:  
I. The boundary between Canada and United States of America is 8,963 km, included the Great Lakes and the Canadian boundary with Alaska. [5]
II. The boundary between Kazakhstan and Russia is 6,846 km.
III. The boundary between Argentina and Chile is 5,150 km.

Longest continuous borders:  
I. The boundary between Kazakhstan and Russia is 6,846 km.
II. The boundary between Canada and United States of America is 6,416 km, included the Great Lakes, but excluded the 2,547 km Canadian boundary with Alaska. [5]
III. The boundary between Argentina and Chile is 5,150 km. 

Shortest entire land border of a country: 
I. 3.2 km of Holy See (Vatican City) (all with Italy – ITVA). [3]
II. 4.4 km of Monaco (all with France – FRMC). [9]
III. 39 km of San Marino (all with Italy – ITSM). [9]

Shortest land boundaries between two countries (total distances, included all fragments) [9]
I. Botswana vs. Zambia (BWZM): about 79 m. [10] (De facto border, not officially defined.)
II. Gibraltar, United Kingdom vs. Spain: 1,2 km.

Shortest international land boundary (country fragments listed separately): 
I. Botswana vs. Zambia: about 79 metres (river border) [10] (De facto border, not officially defined.)
II. Morocco vs. Peñón de Vélez de la Gomera, Spain: 85 meters (Dry land border, without territorial sea boundary). Disputed by Morocco. [9]
III. Bangladesh vs. Natatoka enclave #33/38, India: about 150 metres (Shortest single enclave (de jure) border).
IV.
Märket Island, Finland vs. Sweden: about 527 metres (Shortest island divided by (de jure) border outside mainland baseline.)

True enclaves
Biggest: Isla Apipé Grande, Argentina: 276 km²
Smallest: Natatoka enclave #33/38, India (Cooch Behar): 0.001052 km² (1052 m²)

Country with most neighboring countries by land borders: 
I. People's Republic of China (14): Mongolia, North Korea, Vietnam, Laos, Myanmar, Bhutan, India, Nepal, Pakistan, Afghanistan, Tajikistan, Kyrgyzstan, Kazakhstan and Russian Federation; and
I. Russian Federation (14): North Korea, China, Mongolia, Kazakhstan, Azerbaijan, Georgia, Ukraine, Byelorussia, Latvia, Estonia, Finland, Norway, Poland and Lithuania [2]

1) Northernmost international land border point: The Finnish-Norwegian border between Polmak (Norway) and Nuorgam (Finland) on 70°05'32"N 27°57'00"E at boundary marker 343 in the middle of the River Tana. A few hundred meters towards east where the road (Finnish number 970 and Norwegian number 895) passes the Finnish-Norwegian border is the northernmost land border crossing point. [1]

2) Southernmost international land border point: The Argentine-Chilean border on the southern coast of Tierra del Fuego in Canal Beagle, west of the Argentine town of Ushuaia and north of the Chilean island of Ile Hoste.
The southernmost border marker is located on 54°53'34"S 68°36'30"W, but the southernmost land borderpoint is wet and located in the territorial sea at 54°54'50"S 68°36'30"W about 2500 m further south–southeast.

3) The lowest elevation of a land border: It follows the Israeli-Jordanian, the Jordanian - Palestinian and Israeli - Palestinian boundary lines in the Dead Sea. (Palestine is Israeli occupied, but not claimed by Israel.) In 2013 the sea level was 427 metres below sea level.

4) Disputed.

5) Also the Caspian Sea river border between Kazakhstan and Russia (KZRU) is on the same elevation (- 28 msl).
