Michelle Martin and Ryan Huang kick off the week with a discussion on Berkshire Hathaway's stake in Occidental Petroleum, along with major updates to sanctions on Russia involving banks, Visa and Mastercard, plus Shell defending its choice to buy discounted Russian oil. Next, they analyse China's big NPC meeting, Singapore freezing what it calls 'stolen' crypto, a lookahead to the US CPI and who's taking over Raffles Medical.
