Not long ago, Punjabi-Canadian singer Jazzy B's rings, often the size of a cookie, along with his plus-sized Kanda pendant and silver blonde hair tints, were trending.More recently, the yellow tinted glasses worn by singer Badshah; the baggy hoodies sported by Yo Yo Honey Singh; and AP Dhillon's Louis Vuitton bombers and Chanel watches have been hugely popular with Punjabi youth.

But even though their influence was significant, it was restricted to a region. Dosanjh and a few others like him, however, have managed to mount it to a global level, their style speaking to both the Sikh diaspora as well as a broader audience. For instance, the t-shirts, pearls and sneakers Dosanjh wore to his world tour last year were sold out in a matter of hours. Dhillon's style statements at Paris Couture Week have created aspiration among Punjabi youth.Cultural experts say that this reinvention, both in music and fashion, has its roots in Western pop-culture as most of the artistes live and perform in the West."Punjabi men are inventive. The region has been at the forefront of fusion, it believes in hybridity. This is especially the case with the Punjabi diaspora - even when they live in ghettos, they are the showmen [of their lives]," says art historian, author and museum curator Alka Pande.

The coin dropped instantly back home in Punjab, which absorbed logo fashion like a sponge when luxury brands arrived in the 2000s. For Punjabis - who are largely a farming community - it was an aspirational uprising, symbolic of how success and prosperity should look.

"It symbolised the movement of the Punjabi identity from a farmer to a global consumer," says acclaimed singer Rabbi Shergill.On Friday, Trump announced the tariff rate on steel and aluminium imports would double to 50%, starting on Wednesday.

He said the move would help boost the local steel industry and national supply, while reducing reliance on China.Trump also said that $14bn (£10bn) would be invested in the area's steel production through a partnership between US Steel and Japan's Nippon Steel, though he later told reporters he had yet to see or approve the final deal.

The announcement was the latest turn in Trump's rollercoaster approach to tariffs since re-entering office in January."There will be no layoffs and no outsourcing whatsoever, and every US steelworker will soon receive a well deserved $5,000 bonus," Trump told the crowd, filled with steelworkers, to raucous applause.
