Ukraine matters very much-much more than does Afghanistan, and Afghanistan matters a lot
Re Ukraine tally you cited, add Neon (Ne), a noble gas, produced in the Ukraines ~70-90% of global requirement
Am going to guess that sanctioning Russia by means financial is (1) unlikely to work, and (2) very extremely damaging, but (3) deemed by enough winging-it to be worth a try, without thinking through the logical chain of reaction functions.

Ukraine war flashes neon warning lights for chips Reuters February 24, 20229:57 PM GMT+8Last Updated 2 days ago

MILAN, Feb 24 (Reuters Breakingviews) - Russia’s invasion of Ukraine read more by land, air and sea risks reverberating across the global chip industry and exacerbating current supply-chain constraints. Ukraine is a major producer of neon gas critical for lasers used in chipmaking and supplies more than 90% of U.S. semiconductor-grade neon, according to estimates from research firm Techcet. About 35% of palladium, a rare metal also used for semiconductors, is sourced from Russia. A full-scale conflict disrupting exports of these elements might hit players like Intel , which gets about 50% of its neon from Eastern Europe according to JPMorgan.
The pain won’t fall evenly. ASML (ASML.AS), which supplies machines to semiconductor makers, sources less than 20% of the gases it uses from the crisis-hit countries. Companies may turn to China, the United States and Canada to boost supplies, says JPMorgan. But this may be a slow path. Although the chipmaking industry was able to manage an increase in neon prices stemming from the 2014 Crimean crisis, the scale of today’s conflict looks much larger. (By Lisa Jucca)

Chipmakers Need a Supply Chain That Avoids Ukraine

The crisis in Ukraine is a stark reminder of a major flaw in the chip industry’s global supply chain: single sourcing for critical supplies.
As Russia launched an all-out attack against Ukraine early Thursday, semiconductor makers and tech hardware manufacturers were confronting the prospect that a protracted conflict would interrupt the exports of neon gas, a relatively obscure yet vital component of the chipmaking process.
