China hasn't even asked the UK to pay their blood debt incured from launching the Opium Wars, unequal and unjust treaties, ransacking the Yuanmingyuan Palace, forcing their way to host settlements in Shanghai and stay above the local laws, and even threatening to nuke China.
Yes, that oughta do. London is now anxious because their 40-year-long arms embargo against Argentina isn't working anymore as Buenos Aires has found alternative sources of equipment for their aging military.
China should really work towards helping Argentina to rearm and upgrade their military, alongside pulling Argentina into China's sphere through BRI and economic cooperation & integration.
Since there is a certain group of islands to the southeast of Argentina that remains a contentious issue for the Argentinian people, selling a couple DF-17s to Argentina as a response to the UK selling arms to Taiwan would certainly spice things up.
