ULAN BATOR, Mongolia (AP) — China and Mongolia pledged Thursday to almost double their annual two-way trade to $10 billion by 2020 as President Xi Jinping became the first Chinese head of state in more than a decade to visit this sprawling resource-rich nation sandwiched between China and Russia.

China also agreed to give the landlocked country access to ports in its north and northeast, the official Xinhua News Agency said. No details were immediately given.
