I think Uzbekistan is now larger than Afghanistan and should be on the list now. According to Wikipedia 32 million in Uzbekistan and 28 million in Afghanistan. Other bordering countries

Turkmenistan: 5M

Tajikistan: 9M

Kyrgyzstan: 6M

Kazakhstan: 18M

Has Uzbekistan a bigger population than Afghanistan?

The answer is, "Maybe." Different sources claim different populations for the two nations. Ostensibly, the source of this is Wikipedia in which case Uzbekistan is listed as having the slightly higher population.

the UK borders Spain with the Gibraltar strait, so the UK is bordering 2 countries that have a lower population.
