MEXICO CITY, Jan 10 (Reuters) - Mexico's peso weakened to a historic low of 18.01 pesos per dollar in international trading on Sunday, amid concerns over the economy in China and persistent declines in the price of oil.
The Mexican peso slid 16.8 percent in 2015 and has slumped more than 4 percent so far this year.
