Emirates Airline president Sir Tim Clark  believes the US aviation industry would suffer if the system of Open Skies agreements falls apart.
 Clark  says international demand for air travel and aircraft have skyrocketed since the first of more than 120 Open Skies agreements were signed in 1992.
 Emirates Airline president Sir Tim Clark  believes the US aviation industry could become a victim of the trade dispute centered around the Open Skies agreements that govern air travel between the US and the United Arab Emirates where  his  airline is based.
 This  Clark  believes  threatens to weaken the network of Open Skies agreements that have served the aviation industry so well over the past couple of decades.
REUTERS/Satish Kumar "When the US went Open Skies I thought it was the best thing because if the US had done it then everybody would follow suit "  Clark  told us.
"I know that as a result of what they did  the number of planes Boeing sold went nuclear "  Clark  declared. "Because the number of aircraft sold was a direct function of the Open Skies versus closed skies relationship."

[EX Q]: Verify if the sentiment of the following document towards the entity Murphy is Neutral . Sen. Chris Murphy  D-Conn.  blasted President Donald Trump's method of dealing with North Korea in a Wednesday interview.
"It's not surprising that our negotiations are on life support right now. President Trump is deploying what is perhaps the worst negotiating strategy in the history of the American presidency  " Murphy  said on MSNBC's "Morning Joe."
"It's not just that he's out there calling this guy names  " Murphy  said  referring to Trump calling North Korean leader Kim Jong Un "Little Rocket Man."
"It's that he is publicly undercutting his Department of State by tweeting out that Rex Tillerson does not have his support and cannot talk and negotiate on his behalf  " Murphy  said in the MSNBC interview.
 He  said that Trump is correct to point out that the U.S. has a military option.
"But you've actually got to empower your diplomats to do the work  and you've got to communicate that the previous nuclear deals that other presidents have signed are still good. By threatening to back out of the Iran nuclear agreement  you're not incentivizing the North Koreans to enter into their own agreement  " Murphy  said.
"It's a combination of military threats  of real bilateral  multilateral economic sanctions  which this president cannot put together  because he is out there insulting all of the allies who would work with us on sanctions  and empowering your diplomats  " Murphy  said.
" He  is doing none of the things to achieve a real diplomatic breakthrough."
Also on Wednesday   Murphy  is introducing a gun control bill in support of universal background checks  but  he  said  he  is realistic about its chances of passing. "I'm not naÃ¯ve about our chances to pass this bill in this Congress  but it's important to have this as a fulcrum point for the movement  " Murphy  said  according to The Washington Post.

[EX Q]: Verify if the sentiment of the following document towards the entity Cainiao is Negative . HONG KONG/BEIJING (Reuters) - Chinese e-commerce firm Alibaba Group (BABA.N) has taken control of logistics unit  Cainiao  and pledged to spend 100 billion yuan ($15 billion) over five years to build out a global logistics network  underscoring aggressive expansion plans overseas.
Alibaba will invest 5.3 billion yuan to boost its stake in Cainiao Smart Logistics Network to 51 percent from 47 percent  giving it direct control over the loss-making affiliate  suggesting a rough valuation of  Cainiao  at around $20 billion.
âOur commitment to  Cainiao  and additional investment in logistics demonstrate Alibabaâs commitment to building the most-efficient logistic network in China and around the world â Alibaba CEO Daniel Zhang said in a statement on Tuesday.
 Cainiao  was the focus of an investigation last year by the U.S. Securities and Exchange Commission (SEC) into Alibabaâs accounting practices.
 Alibaba  which will gain an extra seat on Cainiaoâs board giving it four out of a total seven seats   added that more shares were issued in the funding round to other investors.  It  did not give details about the other issuances  which would impact  Cainiaoâs  valuation.
The investment also signals  Alibabaâs  intention to boost control over China âs  domestic warehousing and delivery market  increasingly competitive as firms seek to make use of troves of logistics data about the countryâs Internet-savvy shoppers.
In June major logistics company SF Holding cut ties with  Cainiao  which provides logistics support directly to Alibabaâs top e-commerce platform Taobao . SF Holding claimed Alibaba had requested data unrelated to an existing partnership agreement. Alibaba denied the claims.
A person close to Alibaba  who asked not to be named  said  Cainiao  was not currently considering an IPO.
Alibaba and  Cainiao  declined to comment.
Alibaba co-founded Cainiao in 2013  with partners including department store owner Intime Group  conglomerate Fosun Group and a handful of logistics companies. It oversees roughly 57 million deliveries a day.
