European shares rose on Thursday, as artificial ​intelligence-driven optimism offset lingering concerns about a deadlock in US-Iran peace talks, while a high stakes US-China summit was also ​on investors’ radar.

The pan-European Stoxx 600 was 0.4 per cent higher ⁠at 614.05 points, as of 0703 GMT, after rising ‌0.8 per cent ‌on ​Wednesday. Some local markets were closed due to a public holiday, likely keeping ⁠trading volumes light.

Official ​data showed Britain’s economy ​expanded unexpectedly in March by 0.3 per cent. The blue-chip ‌FTSE 100 was up 0.2 per cent.

Despite ​recent gains, European equities remain below pre-war levels, ⁠with inflation data ⁠highlighting ​the impact of higher oil prices on the import-dependent region.

European Central Bank’s chief economist Philip Lane became the latest member of the bank to say interest rate hikes might be required to deal with inflation.
