Beijing has denied trade talks are even taking place despite President Donald Trump’s repeated claims on social media. The president is meanwhile planning to restore his so-called “reciprocal tariffs” on the rest of the world within a matter of weeks and is threatening to walk away from US-brokered Russia-Ukraine peace talks if things don't go his way. International benchmark Brent remains $9 per barrel lower than before Trump’s “Liberation Day” address. It closed at $66.55/bbl on Thursday, down $1.41/bbl on the week, while US price-pin West Texas Intermediate lost $1.89/bbl to finish at $62.79/bbl.
