LONDON, June 2 (Reuters) - Northwest European gasoline refining margins recovered after sharp falls in the previous session, gaining about $1.78 to $22.36 a barrel as trading activity picked up on Tuesday.

• About 9,700 metric tons of E5 gasoline barges traded in the Argus window as Equinor, Trafigura and Exxon sold to Shell, MB Energy and Varo.

• Varo also bought an E5 barge from BP in the Platts window.

• A further 3,100 tons of E10 gasoline barges changed hands, with Petroineos selling to MB Energy.

• China's state planner has allowed some independent refiners to cut output from June, consultancies and sources said, a sign of Beijing's growing confidence that it can weather an oil shock triggered by the closure of the Strait of Hormuz.

• EU-27 and UK gasoline and blending component exports averaged 811,000 barrels per day in May, compared with an average of 954,000 bpd in April, Kpler data showed.
