Input: Consider Input: “Staff are working at a pace that is unheard of (in trade negotiations) ... and any suggestion that we’re not operating beyond a normal pace is just flat wrong ” U.S. trade envoy Robert Lighthizer told reporters.
 Lighthizer  said Canada had “mentioned” the U.S. ruling during talks on Wednesday.
Asked whether the dispute could affect NAFTA talks   Lighthizer  told reporters: “I‘m not saying it doesn’t have an effect on relationships  it does  but not on this negotiation.”
 Lighthizer  said the United States would “hopefully” present draft text by the next round on the thorny issue of rules of origin  which outlines how much of a product needs to originate in a NAFTA country  and on a dispute settlement mechanism.
 Lighthizer  said the U.S. decision on Bombardier still had several stages to go through before it was finalized.
“There are several more stages  we don’t even know whether it is going to be successful  and in addition there are off-ramps in the litigation ”  he  said. “It’s too early to tell.”
 Freeland  has suggested that Canada could walk away from the NAFTA talks over the so-called Chapter 19 dispute mechanism  under which binational panels make binding decisions on complaints about illegal subsidies and dumping. The United States has frequently lost such cases.

Merkel  needed to reassure German voters and businesses they will still be able to trade with the UK .  He  told the paper : “ Approving a higher divorce bill at this stage would be foolish … As for Germany   its domestic political concerns make it less likely that it would want to risk the damage that could be done to its industry from the UK imposing tariffs on its exports .” Mr . Duncan Smith added : “ When you look at what is going on in Europe the idea that out of that chaotic situation can come any sort of understanding is clearly not right   so we will have to sit tight .” May Expected to Offer EU £ 40 Billion – But Leavers Ask : What Are We Getting in Return ? The German chancellor ’ s Christian Democratic Union ( CDU ) and sister Christian Social Union ( CSU ) parties recently suffered their worst election result since 1949   with the populist   right - wing Alternative for Germany ( AfD ) surging . Their former coalition partner   the Social Democrats ( SDP )  also had their worst post - war election performance and announced they would quit the “ grand coalition ” and go into opposition . Mrs . Merkel had since failed to form a government with Germany ’ s Free Democrats and the Greens   with ideological differences proving too great .

Input: Consider Input: Russian President Vladimir Putin  hasn't said if  he  is running for a fourth term. But none of the potential candidates hoping to unseat  him  appear in a position to do so.
The most visible and adept foe of the  Putin  regime  Alexei Navalny  wants to enter the race but is legally barred. TV host Ksenia Sobchak has tossed her hat in the ring  but no one knows if she can meet the registration requirements or if she's effectively a red herring.
 Putin  is expected to wait until December to state  his  intentions. The election is scheduled for March.
 His  approval ratings consistently register 80 percent or higher.
