“We must make every effort to avoid the fall of the first dominoes. There is still time ”  WTO Director General Roberto Azevedo  told the heads of WTO delegations at a closed-door meeting in Geneva.
“In light of recent announcements on trade policy measures  it is clear that we now see a much higher and real risk of triggering an escalation of trade barriers across the globe ”  Azevedo  said  according to a copy of  his  statement released by the WTO.
 Azevedo  is normally very conservative in remarks about WTO members’ trade policies  but  he  also plays a role as a guardian of the global trading rules  a bulwark against protectionism.
On Friday  he  broke  his  silence on Trump’s tariff plan  expressing concern and saying a trade war would be in nobody’s interest.
In  his  statement at Monday’s meeting   he  did not name any one country but sounded a more urgent warning.

WASHINGTON  â Christine Sylvest  looked around Tony and Joe's Seafood Place and saw a sea of maroon and silver.
Nearly 200 others who once walked the halls of Marjory Stoneman Douglas High School flooded the restaurant Tuesday evening in the Georgetown area of Washington  D.C. to raise money and support students and faculty at the school. It wasn't long before  she  saw a familiar face  one  she  hadn't seen in about 22 years.
 She  and Felicia Wivchar  both 39  graduated in 1996 when Parkland  Fla. was still known as a safe  tight-knit community and not as the home to a mass shooting that left 17 dead. Their smiles  hugs and catching up turned bittersweet as they talked about the tragedy and where they were when they heard the news.
