HONG KONG (AFP) - Asian markets sank on Wednesday (April 10) as the possibility of a US-EU trade war shifted into focus after Washington's tariffs threat, while traders are also spooked by Brexit uncertainty.

It also comes despite negotiators holding a series of meetings since last year ahead of proposed trade talks to resolve the dispute.

Prime Minister Theresa May will on Wednesday hear at a showdown summit the EU's decision on her request for an extension to Britain's exit, which is due Friday, and to avoid an economically calamitous no-deal divorce.
While she has asked for a delay until the end of June, EU heads fear that will not be enough and Council President Donald Tusk has suggested up to a year to find a new way around the crisis.
Observers broadly expect a deal to eventually be made, though US Treasury Secretary Steven Mnuchin said a "hard Brexit" remained possible, adding that authorities were preparing for such an eventuality.
The pound is coming under increasing pressure over the issue though it continues to hold its own for now.
Oil prices edged up as Russian President Vladimir Putin left open the possibility of extending a production cut agreed with Opec.
