Trump tells Americans to "buy American and hire American"

U.S. President-elect Donald Trump has reassured Americans of bringing back jobs to the United States and said that his administration will follow two simple rules

"My administration will follow two simple rules: Buy American and hire American."

"The American worker built this country and now it's time for American workers to have a government for the first time in decades answers to them," CNN quoted Trump, as saying at his rally in Des Moines, Iowa.

Officially introducing Terry Branstad as the new US ambassador to China, Trump said that he has chosen a man who knows and likes China.

Asserting that Branstad he has been delivering results for 23 years for the great farmers and people of Iowa, Trump said he knows how to deliver on results.

Trump's transition team had said that Branstad was selected as envoy in Beijing due to his experience in public policy, trade and agriculture as well as his pre-existing relationship with China's leaders.

During his rally, Trump said that improving relations with China would be one of the most important goals of his administration.

"The nation of China is responsible for almost half of America's trade deficit ... they haven't played by the rules and I know it's time they're going to start. We're all in this thing together folks. We have to play by the rules folks," he said.

Trump has accused China of stealing US jobs and has criticized

Beijing over currency devaluation and tariffs during his campaign.

Trump had last week angered China by taking a congratulatory call from the president of Taiwan .

The Republican also said that he would suspend immigration from places "where it cannot be processed or vetted."

Trump said he wants people to come legally into the country.

"And to all veterans who wore the uniform before, I say to you now on behalf of a very grateful nation, thank you, thank you thank you ... We'll honor your service, your sacrifice."And that really begins with defending and respecting our American flag. I think you'll like some of the things we'll be putting forward in the not so distant future. You know what I mean?", Trump said.

The Republican also honoured US senator and astronaut from Ohio, John Glenn, who died on Thursday at the age of 95.

Trump said it was John Glenn who immediately enlisted to defend his country when Pearl Harbor was attacked and they will honour his legacy by continuing to push new frontiers in science, technology and space.
