"The price of the wall will be paid, either directly or indirectly, or through long-term repayment, by Mexico, which has a trade surplus of $ 71 billion with the United States," Trump said in a twitter comment on Thursday. The $ 20 billion wall does not mention the size of Mexico's trade with America. " 
"The plan to build the wall will not change since it was declared, and parts of it will necessarily be transparent," Trump said, denying that it would be built "in areas where there is natural protection such as mountains, lands, difficult rivers and water."
