MEXICO CITY - Japanese Prime Minister Shinzo Abe wrapped up a two-day visit to Mexico on Saturday, taking a break from sealing energy deals to tour pyramids with President Enrique Pena Nieto.
Mr Abe and Mr Pena Nieto visited the pre-Columbian city of Teotihuacan with their wives Akie Abe and Angelica Rivera de Pena, donning palm-leaf hats and posing for pictures.
The couples did not speak with the press.
But Mr Pena Nieto's office released a statement saying Mexico expects greater trade and cooperation with Japan in coming years.
Mr Abe struck a series of energy deals Friday with Mr Pena Nieto at the start of a five-country Latin American tour.
Mr Abe, whose visit to the region comes on the heels of one by Chinese President Xi Jinping, inked a deal between Mexican state oil firm Pemex and Japan's development bank, and another between Pemex and the Japan Oil, Gas and Metals National Corporation.
With Japan on the lookout for new power sources after the Fukushima disaster forced the shutdown of its nuclear reactors, energy is high on the Prime Minister's trip agenda.
Mexico is undergoing sweeping changes in its energy sector, with Congress poised to end struggling Pemex's 75-year monopoly and open up the oil and gas sectors to foreign investment.
Japan is Mexico's fourth trade partner, with total trade of US$19.3 billion (S$24 billion) last year. There are some 800 Japanese companies that have investments in Mexico, especially automobile giants like Nissan, Mazda and Honda.
Mr Abe is the first Japanese leader to visit Mexico since Prime Minister Junichiro Koizumi did in 2004.
Mr Abe's nine-day trip - which will also take him to Trinidad and Tobago, Colombia, Chile and Brazil - comes just days after China's Mr Xi wrapped up his own four-country tour of the region.
With its emerging economies, Latin America holds promise as a relatively untapped market for Japanese exports, in addition to its coveted raw materials.
