A Mexican cement maker is ready to lend its services to US President-elect Donald Trump to build the wall he wants to erect on the southern border of the United States to curb immigration. ?We can?t be choosy,? Enrique Escalante, Chief Executive Officer of Grupo Cementos de Chihuahua (GCC) said in an interview. ?We?re an important producer in that area and we have to respect our clients on both sides of the border.? Republican Trump campaigned vowing to build a ?big, beautiful, powerful? wall across the 2,000 mile (3,200 km) frontier in order to stop illegal immigrants from Mexico, which he accused of sending rapists and drug traffickers north.
