What is the sentiment of the following document towards the entity Kim Jong Un ? WASHINGTON/SEOUL (Reuters) - U.S. Vice President Mike Pence was scheduled to meet with North Korean officials  including leader Kim Jong Unâs sister  while in South Korea for the Winter Olympics this month but the North Koreans canceled at the last minute  U.S. officials said on Tuesday.
Pence was going to meet with North Korean leader Kim Jong Unâs younger sister  Kim Yo Jong  and the nominal head of state  Kim Yong Nam  but the North Koreans called off the Feb. 10 meeting two hours before it was set to start  a U.S. official said  confirming a story first reported by the Washington Post.

âThis administration will stand in the way of  Kim âs desire to whitewash their murderous regime with nice photo ops at the Olympics. Perhaps thatâs why they walked away from a meeting or perhaps they were never sincere about sitting down â Ayers said in the statement.
 Kim Jong Un   through  his sister   invited South Korean President Moon Jae-in to Pyongyang to begin talks âsoon.â
answer:
Neutral


question:
What is the sentiment of the following document towards the entity Marat Safin ? And with a mangled racket and plenty of kicking and screaming  including a couple of arguments with the chair umpire  then a postmatch parting shot at a line judge Safin called "a little bit too blind."
 Safin used to rant about disliking tennis on grass  and he once complained about the high price and low quality of food at the players' restaurant at the All England Club. Well  he doesn't have to worry about any of that again after bowing out in his final Wimbledon with a 6-2  3-6  7-6 (4)  6-4 loss to Levine.
 After confirming this would be his last appearance at the grass-court Grand Slam tournament -- Safin has vowed to retire at season's end -- he was asked how he feels about being done with Wimbledon.
 He's a former No. 1 player who won the 2000 U.S. Open and 2005 Australian Open  but a series of injuries slowed him recently. Still  Safin came to Wimbledon ranked 24th and seeded 14th  and had to be considered quite a favorite against Levine  who never had defeated anyone ranked better than 67th.
Safin has vowed to retire at season's end -- he was asked how he feels about being done with Wimbledon.
 He's a former No. 1 player who won the 2000 U.S. Open and 2005 Australian Open  but a series of injuries slowed him recently. Still  Safin came to Wimbledon ranked 24th and seeded 14th  and had to be considered quite a favorite against Levine  who never had defeated anyone ranked better than 67th.
 "He's an amazing player  and I'm still kind of feeling weird right now that I just beat Safin  because I've always watched him play on TV " said Levine  who turned pro in 2007. "I just kind of went out there with nothing to lose and played some good tennis."
 Levine was a teen when Safin burst onto the scene as a brash  big-hitting 20-year-old who knocked off Sampras to win the U.S. Open.
 "I really had to ... focus on playing against the ball and not worrying about  'Oh  wow  I'm playing against Marat Safin on the other side of the court '" Levine said. "Because then things could have gotten a lot more interesting."
 As is his wont  Safin made things interesting enough. In the early going  he broke his racket by spiking it on the court.
 Leading 4-3 in the third-set tiebreaker  Safin hit a shot near a line that was ruled out. Afterward  Safin said: "Thanks for the guy who made the call. I want to say hello to him. Too bad that he was a little bit too blind."
 In the fourth set  Safin told the chair umpire he could check for chalk on the ball to confirm a call. Rebuffed  Safin added: "So all players are stupid?"
 Safin reached at least the semifinals at all four majors  including at Wimbledon last year  but he has been criticized for not living up to the potential stored in his 6-foot-4 (1.93-meter) frame -- about 7 inches (18 centimeters) taller than Levine.
 "In the history of tennis  everybody's an underachiever " Safin said. "Agassi should have been winning  I don't know  15 Grand Slams. Sampras should have been winning 20 Grand Slams. Federer should be winning -- already should have 25."
 "I should probably have (won) a couple of more " he said  "but I'm pretty satisfied with what I did."
answer:
Negative


question:
What is the sentiment of the following document towards the entity Christopher ? Christopher Chin wasnât necessarily expecting a life-altering moment when he flopped into the waters off Viti Levu  Fijiâs largest island  in his diving gear.

Heâd joined IMAX filmmakers Howard and Michele Hall on a dive to film sharks. Not long into their second-day dive  the trio was surrounded by sharks â as many as 12 different species.  Christopher  descended into a theater-like plateau  at about 32 meters  when a bull shark emerged within armâs reach â its penetrating black eyes locked with his own.
âThis was a sentient being  an animal trying to figure out what I was doing there â recalls  Christopher   a Workday engineer. âI knew sharks were troubled and misunderstood â but I didnât realize to what extent.â

When  Christopher  emerged from the water   he  paused.  He  knew  right then  that  he âd be on a mission in life to teach people about these mysterious animals â and our oceans at large.
Indeed  a few years later  he  founded a nonprofit organization called COARE (The Center for Oceanic Awareness  Research & Education).  Christopher  has been featured on the Discovery Channelâs Shark Week;  he âs a top expert on shark fin policy in North America  and one of the nationâs leading experts in single-use plastics legislation.
âWe all depend on the ocean  no matter where we live â  he  says. âWe depend on it for sustenance  for the very oxygen we breathe. And the ocean depends on us â no matter where we are  or the things we do  we can take little actions that have a tremendous impact on the world around us.â
Last year   he  spoke at the United Nations:
 Christopher   a scuba instructor and technical diver  was drawn to the ocean at an early age.  His  father was a diver who worked for the former Pan American Airways (Pan Am)  which enabled diverse experiences around the world.
âThe underwater world has always fascinated me â  he  says. âOnce I became a certified diver  I never looked back. I did 100 dives in my first year.â
With the founding of COARE   Christopher  has an outlet to share  his  passion and knowledge â and compel others to act with responsibility and urgency.
âProtecting our oceans is challenging and daunting â  he  says. âThere is a lot of waste. But as an organization  we just try to walk our talk. Even in the conservation community  weâll see a speaker up there with a single-use Starbucks cup â itâs hypocritical. It drives me bonkers!
 Christopher  has been impressed by Workdayâs own commitment to sustainability.
âIâm proud to work at a company so dedicated to reducing its environmental impact that it has full-time employees dedicated to creating  improving  and promoting sustainability efforts â  Christopher  says. âThese efforts  from the rechargeable battery program to reusable snack bowls make a measurable and meaningful difference with little effort.â
Outside our walls  thereâs an ever-evolving fight to break old habits. And  Christopher  is often right there  making the case for positive change.
answer:

Positive
